Ohhh, your friend is right about the reflectors. Reflectors in the spokes end up being an annoyance anyway. Stylewise, it shouldn't matter if they are on a hybrid. Leave them on the hybrid.

Jerseys are a matter of taste. Most roadies prefer jerseys. I didn't until I started wearing jerseys on a regular basis. They are much more practical -- pockets in the back, they don't retain as much sweat, and some actually look pretty cool (that one could be debated). Most jerseys do not fit me well -- an example can be seen in the "RAGBRAI" post! I run into a problem with the jerseys I have because the group ride I participate in is sponsored by a bike shop. Most of my jerseys were given to me and they have the name of other bike shops on them!

Styleman SUCKS!
