3/4 length jacket or waist cut jacket.

Why not just buy the one that feels good to ya? That fits YOUR needs?

Long for touring, short for town / local. If you have to pick one REALLY good as it appears, go with the long. Lots of nice short jackets with good clearance pricing that work good. I'm sure you know all the closeout sites.

I have a long torso, so a lot of short length jackets ride up above the belt line. For that reason, I usually find 3/4 length more comfortable.
