From what I have figured so far the 1900 rear end will be good for generating grip and therefore would be better suited to a lighter body weight. When running the heavier bodies the 1700 will work better with the solid back end.
Team list updated. With Michael still looking for a drive, he can joking team armchair if their third can't make it or make a four man team. The slotworx shield will be up for grabs.
