I came to the conclusion 2 or 3 months ago that I would like to take Fundies and, eventually, get a Tech pass.
When I do take that class, I will modify my rig in whatever ways are required by the instructor, no problem. If I have to remove my AI transmitter, no problem.
When I'm done with the class, I'll keep whatever changes I feel make me a better diver and get rid of the changes that don't. I don't think having AI makes anyone a better or worse diver. Everyone should have an SPG. I fully expect that after the class is over I will put the AI transmitter right back on my rig and move on.
My motivation for taking the class is to improve my diving skills (buoyancy control, trim, etc.) such that they become good enough to earn a Tech pass. Learning new mental skills is great. Having additional tools in the toolbox is generally good. But, I feel pretty confident when I say that, if/when I earn a Tech pass, I am not going to start limiting myself to using standardized gases, calculating my ascents in my head, etc..
I'm pretty sure I can have a drink of the Kool-Aid without becoming addicted. ;-)
