Welded front sucks, but like someone said, a detriot probally isn't much better. Definitely go hydro assist. I'm hoping to add this before christmas.

Also, as a side note, if you're running longfields or some other beefed up birf, you really don't want to run a locker unless its a selectable one (or solid). The reason being is toy lockers were designed with the weak birfield in mind. Now with the weak link removed, the breakage point goes up, and so does the amount of whiplash that goes with it, which kills nonselectable lockers (detriots, lockrights) for some reason. Spools, arbs, e-lockers, and welded fronts do not seem to have this same problem, most likely due to the lack of that racheting device. Read up on it at PBB. Alot of people are killing detriots with these things, and I know busa killed whatever he had in his front when he broke an axle shaft at k-rock.
