When I went from Bauer Flexlites to VH both on LS2 steel, I went from 1/2 to 5/8 and kept that for 3 years. With my new pair of VH skates with Step steel, I recently went to 11/16 and it's working very well for me. I don't know yet if I'll try 3/4 at the next sharpening. And for reference I only weigh 140-145 lbs.
