All minel were great. Good right out of the box and great after break in. BID, I savedfor the $40 & $50 B17 standard models with small, steel rivets and black or chrome rails. They generally broke in within 400 to 500 miles and leather wasn't as heavy.
Later I got the Champion Specials with large, hammered rivets and skived edges. They had very thick, heavy leather as did the Professional model I had. It took them thousands of miles to reach that sweet spot, but they were OK from day 1. Don
Most comfortable I ever rode was the B-72 on a Raleigh Sports I had back in the 80's. It had deep sit bone indents that were soft and pliable while the main body leather was still stiff & held its shape. Don
