This to short?

Hey everyone,
I just recieved a M4 merrick its 6'0 18 1/2 wide and 2 1/4 thick. I am 5'10 149pounds, now i do like to ride my boards short. My other board (which is currently stuck in santa cruz...fleshin' airports)is a flyer 5'11 i loved it. Anyways is this board to small? My frontside feels great but my backside gets bogged sometimes (especially in high tides)compared to the flyier. Thanks for any opinions posted.
