as for workability, the 22's rear end can be a pain. Now that I'm running the DEX210 it seems a bit better, but not much, to change the anti squate on it is like changing toe on the 22, you need to un bolt alot of stuff and flex it a bit, hopefully not shooting shims and inserts every were, so the 22 isn't the only one like that. I'm not sure what the cougar is like, but I know the xxx-cr was a peice of cake, and I think the B4 is similar. The X6^2 also seems pretty good with the ability to keep the motor plate in place and remouve just the tranny, very slick. In short, just get an electric screw driver for tear down and 80% of the re assembly, save the last 20% to do by hand.
