I've actually been fortunate enough to ride all of the choices you've listed. (When I've accomplished and especially difficult task or reached a goal, I reward myself with a test drive of a new car or a test ride of a bike I've not yet ridden.) I don't really think you can go wrong with any of the four. Now if you really want to have some fun, check out e-bay to see what they got listed in something your size. I find that on non-riding days I can spend lots of time "window shopping".
