I've got a set of rims in mind for my next much needed upgrade (alex supra's, aka azonic outlaws, performance loco, etc) and the pinned version (BH) are $20 cheaper than the welded (D). I was just wondering if anyone has compared a pinned version of a rim to a welded version of the same, and how much of a difference there is. These Alex rims sound killer, only 590 grams each and reportedly super strong. So are the welded worth the extra $?
