sure get what they recommend if that's what it calls for. There are other options that most definatly won't hurt your saddle too. As I recall they are still made of leather aren't they? Leather is nothing new and you don't need anything fancy if it costs too much. When I was learning taxidermy techniques I was taaught by an old pro that used properly plain old lanolin will keep it beautiful and supple for a long, long time. If it's good enough for a 60 year old stuffed spider monkey it's good enough for your saddle.
