What is the best stock for FT? The one which fits you the best.
To be honest, if you're getting into FT and have an EV2 already, I'd spend a season using the standard stock. That way you will find out what you want in a stock; you might find you get on well with the EV2 stock. It will take quite a few shoots just to get all the different adjustments (cheekpiece height and rake, hook position, hamster depth etc) just right for you.
