Hey, I recently bought smok G-PRIV, and running smok big baby beast with it, tho Im trying to learn and understand this stuff

, currently as I understand my coils does not allow to run with temp mode, and the coils are kinda old, so I am thinking of getting smok cloud beast, that one does not run with temp mode as well only W, well unless the custom RBA thing right? (I am not really planning to mess with that, unless its safe to do?) my questions are:
1. Does it require knowlage and safety issues to mess with the RBA?
2. Is temp mode on vape making the vape better or its just another way of using your coils and the taste is same?
3. If temp control is worth it, which head should I pick that goes well with smok G-Priv?
I cant wait for your answers! Thanks in advance.
Temp Control on any mod, requires certain wire materials, namely Ni200 Nickel (all TC mods support this, but most newer mods support more which the G-Priv does, TC only mode), Ti1 Titanium (TC only Mode), or SS316L Stainless Steel Wire (TC or Wattage Mode very flexible in settings it can be used at), the G-Priv being newer should support all 3 of these wire types. TC is a little more advanced that Variable Wattage, the special wires needed have resistance curves when heated that the mod can read in real time during firing and as resistance increases drastically with these wires when heated, the mod is able to calculate a guess what temp the wire is at, once the set TC Temp Cap is reached it Pulse Width Modulates the voltage signal to maintain that temperature without continuing to increase temperature higher as VW mode does. TC mode is there if you are worried about the different chemicals produced in a vape, namely at certain temperatures can cause scorching of the wicking which can create formaldehyde and other chemicals, setting the TC Cap setting below that temperature, even with a dry wick the mod will not go into that zone of creating formaldehydes and such. Just like VW mode, you have to set a max wattage you like, but with TC mode you have to dial it in even further, starting low TC cap and increase it every few vapes until you hit that pizazz spot in flavor, vapor, and throat hit you like.
TC mode can seem a little weaker than straight VW mode does as it doesn't get as hot as standard VW mode, thus why a lot of people do not like it, it reaches set TC cap and maintains it there. As far as tanks and such that have TC mode coil heads, you'll have to research what it out there as most if not all will work on the G-Priv given the tank to mod connection is a standardized 510 connection, example the Joyetech Ego Mega One Tank would work and does have Ni200 and Ti1 coil heads available, though not as airy as the Baby Beast, there are other tanks out there that have Ni200, Ti1, or SS316L coil heads, so just have to research and find one you might like. To make the Baby Beast TC capable, yes would need to use the RBA head, which is a little more complex and you would need to purchase the supplies and tools needed. Namely a jewelers screw driver set (which can be used as mandrels to wrap the wire with, generally comes in a set of 6), flush cut wire cutters (can find these are beading supply stores, hobby stores, and electronics stores), maybe a pair of needle nose pliers, pair of good sharp scissors, some organic, unbleached, non-peroxide treated cotton (cotton balls, Ko Gen Do or Muji Japanese Cotton Pads, Cotton Bacon, Rayon Cellulose Cotton, etc), and some SS316L wire in two gauges to start 28awg (thinner with higher resistance) and 26awg (thicker with lower resistance) to practice with, you can use the mod as an Ohm reader until you can buy a dedicated Ohm reader. A good investment would be a small package of #14 Machinist Screws (there are a couple of methods of wrapping coils side by side contact where all wire in the coil is touching the neighbor wrap, and spaced with gaps between the coil wraps, TC works best in spaced set up to be most accurate) which will help wrapping the TC coil uniformly.
After that you should get on Youtube, there are dozens of videos out there on how to wrap a coil, mount it, and wick it, it just takes practice, investing in a cheap clone RDA (rebuildable dripping atomizer) is highly advised to practice with, the deck is larger and it doesn't take your tank out of commission while you are practicing.
Safety issues, google and read up on "Ohm's Law", as we deal with electricity this Law of formulas come into play with vaping, the two formulas we use the most are "Fresh Charge Voltage/Resitance=Max Amps (Unregulated and Mechanical Mods)" and "Watts Set/Lowest Voltage Before Mod Shutdown/90%=Max Amps (this is for Regulated Mods which you G-Priv falls into this category)". Reason a focus on Amps, is the batteries are the limiting factor here, go over their Continuous Discharge Rate in Amps, can lead to disasters and expensive hospital bills if not careful, learning to rebuild on a regulated mod adds all its safety features in to decrease this hazard. Know what your mod can handle for resistance (Ohms), most the range is 0.1ohm to 3.0ohms, Ni200 some mods in Ni200 TC Mode can handle 0.05ohms and up in that mode only, Ni200 has very, very, very low resistance per inch compare to other wires, thus why I suggest SS316L as it can be used in both TC and Wattage modes and a bit easier to work with. You'll need to learn to trouble shoot any problems, if the mod kicks a short or no atomizer error you'll need to learn to diagnose what is the problem from the coil connections down through the tank to the mod if it does. Rebuilding isn't that hard, just takes time, practice, and willingness to trouble shoot any problems that arise with error codes and such, first few coils may seem ugly and lack luster compared to Ytube vids, but that is where the practice comes in, if you are getting on in age, having a magnifying stand or magnifying visor helps out immensely (speaking from experience here as my older eyes are not what they used to be).
