Hi. I'm new to the fixie/ single speed thing. Actually I'm new to road bikes all together. I know nothing. I've been into bmxing for 6 years and have a fit hawk frame with a bunch of random parts; fit, tree, profile, odyssey.

Basically i was wondering what good are good frames to convert into fixies?
From what I've already gathered a steel frame with horizontal dropouts? anything else?
I'm poor. and fat. and 5'10, whats a good height for me?
