i can honestly say that ive had an fmf, on my first blaster, and then switched to an lrd, and then on my one i just sold i had a toomey on that.
if your going to go crazy with performance like a 32 mm carb, stroker, 240 kit, ect get a dyno port, or a trinity pipe, or an lrd.
if your just going to get little stuff, 28mm carb, reeds, gearing, get a toomey! i had my toomey and loved it.
