My new saddle keeps slipping to the right, I've checked with my saddler (Kay Humphries) and she says that as the old one did it too it's probably due to TC's shape. I currently use a Nuumed Hi Wither Propad saddlecloth as recommended by Kay but the saddle is still slipping badly. Kay says she is reluctant to alter the saddle (it's a BS/KH Holistic so has a Flexitree) as in 3mths TC will probably be a different shape. So I was wondering what is the best anti-slip numnah or pad to try? I don't want to go buying one that won't work!!
