Well I "rediscovered" something I'd already known about the firehawk. External editing can only be done via android or iOS. Not win and not any flavor of OSX. While I do have an android phone it's smaller. It would be cheaper for me to buy a chromebook to edit the thing then ipad. It also would be easier as my android phone isn't very large. My needs for a laptop/tablet have changed through the years after leaving support..... But that's a story for another day.
Yeah, I've read countless things on issues with string gauge changing on older variax guitars. Not much on trying it with recent ones.
I too would always play 10's on my solid bodies and 12's on my jazz boxes. It was oddly my gigging days playing the blues and advice from a friend that I try going to a lighter gauge. That was the tipping point for me when I could finally do some serious country bends all night long. Which even though I don't consider myself a country player converted me to playing with lighter gauges thereafter (it also helped to speed up my chops)
Regarding performing with various guitars...... I'll never perform live with an acoustic ever again. Not only have I had issue after issue with acoustics through the years. But I've had not one but two "Belushi" moments playing acoustics live.
My 30+ year old strat would need work before it saw the stage. The 9th fret is all out of whack. What's more the finish looks horrible. For the price of a refinishing job I could get two or even three new american made Strats. Actually I could prolly get a 920D custom shop replica of my Strat (as fender no longer makes em that way) for less then I paid for the original.
As for carrying around picks it's just natural for me. If I'm playing with a pick, when I'm done it goes into my pocket and when I change pants the pick, coins, keys come out of one pair and into another.
