Awesome write up, Ozonation! That saves me from doing a step by step writeup that I was going to start tonight!
I will post some info on my experience though since I bought the grip shift version where no cutting is needed. BTW, my hand is the perfect "width" to rest fully on the grip shift version....actually looks like the same hand surface clearance as your hand on your newly cut grip.
I'm excited to start installing mine tonight! Yours look really nice installed! Nice job!
