I'm 5'6", 115 lbs, and I love my B66(male version of B67, same width, just a tad longer than B67). Of course, I ride on a very upright posture and absolutely abhor any "bent" riding posture. If you got no issues with the flyer and ride a more aggresive posture, I say go for that one. On the other hand, since you already have one, I say go for the B67 just to try something new, then return if if you don't like it. Who knows, you just might like the B67 better than the flyer.
