guess it boils down to quality and price ..i mean street wise like riding to work and what not i can use what i got, race wise just use the 1 or 2 piece...there are some good deals for sure on the wera site...its just a matter of getting the right deal and size and what not...being 6.1 and 220 pounds (give or take) id prob have to opt for a 40ish or something..
