Replying to Bindings center mount or man. rec.?

i just bought the 05 armada AR5's (176), and im struggling to decide where to mount them. i know alot of pros like to centermount, but im not sure if id like it.
i also have a pair of 04 Mike Nicks (171), and 05 Flites (172). i mounted the Nicks on manu. rec., which is 2 and a half inches behind true center and love them. they will prolly remain my spinning skis.
the flites have to stay way back at man. rec. also.
the AR5s i plan for ripping groomers and hitting the larger jumps in the park.
man. rec. is 2 inches behind center.

so here is my question, who all out there has ridden center and man. rec.?
tell me what you like about both, and what you dont like. the more specific the better.

ok, now back to my Bell's Amber Ale...Horray beer!
