i have a cove handjob im 5 foot 10 and its a large.i always wonder if its too big or not.when ive been riding the medium trance and get on the cove it feels long but i get used to it then it feels ok.cant help but wonder what a medium would feel like.am i just geting caught up in the fact that i normaly ride mediums because its not much longer if at all than the trance and inbred just abit taller but then i run a very high post on the trance.is there a true deffinate way of me knowing or just the feel of it?

Feel I think.

My 18 inch Inbred feels fine, if anything slightly little but my 17 inch coiler feels spot on. Then again they are different bikes for different things and as such the sizing will be different.
