I remember back in the day...
The center pin wobble is normal for the A7, but I've never had any problem with that. (and I use them on mechanicals) The pin would have to be extended out a long ways before it could touch the ground. (or a mod pin that pushes it to the side) I believe there would have to be something wrong with the center pin of the mod before you would have to worry about one shorting out.
The real trick to setting them up is making sure that the coil is properly placed over the air flow. If the coil is to low, the air flow will only get the center wraps of the coil, and you will get an uneven temperature across the coil.
Because you use thin wire for the coil, rewicking is not a good option, so I use silica string for wicks.
A 6/7 wrap of 30ga around 3 strands of 0.8mm silica string gives me a 1.8 ohm coil. I use a paperclip to wrap my coils which insures that I don't wrap the coil to tight. (which would choke off the wicks)
A 1.8-2 ohm coil in the 3.7-4.1v range is where the A7 will produce the best flavor. (it will make you use less flavoring in your formulas) Flavors like green apple I use 1 drop/2ml of 50/50 mix @ 12mg. Flavors like hazelnut I use 1 drop/1ml.
