I have the choice to buy premade coils right now but what is the perfect ohms to get good vapor production while also not burning through juice like a mad man.

What's perfect for one is awful for another. I'm afraid no one can answer your question but you. Not knowing where you are right now in your vape journey and what type of equipment you are intending to fire those coils with, I'm afraid we're all at a loss to help. Post more info and maybe some can post some opinions.

Welcome to ECF, swinny...

Aside from the preferential perspective, a more safety oriented view requires a bit of electrical knowledge.

The lowest resistance you can use is based on the capabilities of your regulated APV, or with an unregulated mech mod, the continuous current capabilities of your battery.

For example, with a 0.5Ω net resistance build, Ohm's law requires a mechanical mod battery, at 4.2v, to have at least 8.4 amps for resistance parity. To match the Ohm's law parity with a regulated device, you'd need 35 watts.

Once you've got a better handle on that knowledge, then like previous posters advice... it really is personal preference. ;-)

Hi swinnyand welcome to ECF!

The above are good observations. Also, if you use the same power setting juice and vaping technique, lower ohm coils (besides providing a different vape) will go through juice faster than a higher ohm coil will. If the coils are vastly different, you'll likely be using different power settings, though.

Hope it helps and Happy Vaping!
 
Net resistance doesnt matter much with a VW device, unless you are planning to go very low in wattage. Since you jumped off with a 100w device, I'll go on a limb and guess you're not planning on vaping at 5 watts. So in the end, any resistance coil will do just fine as long as it's within the specs of the mod. Somewhere between 1.0 and 2.0 ohms is fine.

I haven't got the mod in my hand yet but i purchased an ipv4 and as of right now i have 50/50 juice

An IPV4 is considered a "high-wattage regulated box mod". That doesn't mean you have to use all that extra wattage, but its there is you need it. I'm glad you chose a regulated mod over a mechanical mod as your first device; it will have protection circuitry to help keep you out of trouble as a beginner. Your mod will refuse to fire your coil if what you request is against Ohm's Law and provide an error message to alert you why your request was refused. A mechanical mod would not do that.

You could put nearly any juice delivery device on your IPV4: clearomizer, cartotank, or rebuildable.

Proper Terminology: Juice Delivery Devices

You don't actually buy "ohms". Ohm is the specification of resistance of the wire coil that your juice delivery devices uses. What ohm coil you choose to use on your IPV4 will depend upon the type of juice delivery device you are using. For example, you buy lightbulbs with a specification of "watts".

Clearomizers and cartotanks typically use "normal resistance" coils in the range of 1.5 - 3.0 ohms.

With "rebuildables" (you make your own coils and wicks), it can be anywhere between 3.0 ohms all the way down to 0.3 ohms. It just depends upon what you will eventually decide what YOU like after experiencing it. Some people like a very warm vape (lower resistance) and others like a more cool vape (standard or higher resistance).

Should you go the rebuildable route, I always suggest starting out making an overall resistance of 1.0 ohms until you get some experience under your belt. Then, should you decide to experience "sub-ohm", work your way down.

Information Resources for Your First RBA

What batteries did you choose to use in your IPV4? They should be IMR or high drain batteries with at least 20 amps continuous discharge rate.
