I have no experience with LaPera, but I recently purchased a Mustang seat for my FXSTC through the internet sight unseen.
The first time my wife went to get on the bike, she's 5'2" tall, she dragged a foot across the New Mustang seat and the paper thin leather split open like a cheap bag of potatoe chips. I was shocked at how thin the leather was. We've superglued the 3 corner tear down so it doesn't spread, but the aesthetics are gone. If possible look at what you're going to buy to make a determination as to it's durability. I wish I did
