depends on what kind of riding you want to do and the geometry you would prefere your bike to have. the khs has a tighter geometry and would be a little more appropriate for the track. although i do like hte way the filmore looks i think the geometry defeats the purpose of having a fixed gear specific bike. it is basically a road frame so with that in mind i would suggest just buying a badasss road frame and making a conversion. my 2 cents.
