English Saddle: Knee rolls vs None?

What do you think? I'm personally more comfortable in a saddle without knee rolls, calf bocks, etc. I have a Collegiate Graduate with a plain flap--no knee rolls, no calf blocks, nothing. I've rode in this saddle for almost 10 years, so anything else just feels unnatural. If you can ride on a plain flap, you can ride on pretty much anything. All that extra support just makes riding so much easier, and I feel that until you can ride without them, you can't really ride at all.
