this rockhopper comp feels too...big. i always feel like i'm riding "on top" of the bike, as opposed to "being part" of the bike. make sense?

i'm 6'2"....185 lbs...and this is a size 21 frame. i feel like i'm stretched out too far from the seat to the bars. should i try for a shorter stem? sell the rockhopper, and move to a better bike...maybe used? hmm...feel held back from advancing in my riding due to the awkward feeling...too bad the ride was comfy in the parkin lot...or else i would have gone with a smaller frame.

open to suggestions.
