I made severial mistakes over the last few years w Brooks saddles:

1. Very Old B-72, I used neetsfoot oil and proofide. Got caught riding in the rain and riding with the saddle wet. the leather around some of the rivets started to tear.

2. Spontanious Spash and Dash got the better of me and now there are stains on a honey champ flyer. I had this saddle since new and have used Proofide exclusively and periodically.

Other notes:
1. saw lots of brooks and Wrights in Amsterdam that appeared to have been lefted out inthe rain and snow forever. Many were totally sagged but strangely not torned
2. Snowprof is good stuff, used it on my leather jackets for over 20 yrs
