I guess it depends on your riding style first of all. Since I am not a smooth natural/comps style rider so short wheelbase didn't work for me. I'm about 6ft also. Plus you have to decide which bb rise is better for you. Some people like high rise bb, some lower rise. So you should try friends bikes if you have a possibility. Choosing everything correctly is important. When you choose frame you add fork which might change geo of the bike, slighty but stil change the feeling (already experienced that). And than, after you got your frame and fork very important is stem. If something i wrote is illegible or not understandable just say. P.S. I'm not from UK so feet and inches are not the measurements I'm used to.
