expense mostly. its ~$1000 for just the bare knuckles. i figure i could pick up a 44 and modify the knuckles for half that. almost every part ive looked at for 60s costs more than 44s and i dont think ill need the extra strength running 33s or 35s. im looking into running a toy/d44 hybrid but itll be on my dd so the balljoints possibly fubaring my frontend worries me a little. a toy/d60 would be nice <img src="/forums/images/graemlins/smile.gif" alt="" />but thats a little out of my price range <img src="/forums/images/graemlins/frown.gif" alt="" />.
