I have talked to Amanda at Aero in Scotland, Mark Moye from Aero USA, and A few people from Schott and Cirrus. I cannot get a straight answer. Some prefer horeshide, some prefer steerhide, but each has their own opinion of what is tougher, more weather resistant and longer lasting. Can someone give me a straight answer? Why do most people prefer horsehide to steerhide other than for historical accuracy?
