shultsy24 give me a shout if you need help when your gear comes in. Also post questions here as well, we all here to help. Congrats on being off the coffin nails.
For me when I have a juice that lacks in throat hit, I bump the power, if that does not help I take a small bottle and add a little VG to it to help increase the TH, keep in mind this can dilute the flavor. The advantage of vaping (or disadvantage) is that taste is subjective and you have a lot of variables especially compared to the coffin sticks. Meaning when you buy a pack of cigs it is what it is, you have zero control of any of it. With vaping you have so many other things that you are in control of; resistance, power to name a few.
My advice is when you get your shiny new gear, slow down and take a moment. Read the instructions if it comes with any, clean everything that juice goes in with vodka and water. Get a feel for what is like to assemble and disassemble (leave them empty for this). Remember snug is good do not tighten anything on with force.
I realize none of this is new for you as you are already vaping. I'm just recalling some of the issues and mistakes I made when I was starting out.
