I don't think you have anything to worry about with a topper either, but there is just something about a full cap that makes you feel VERY secure about your attachment. Maybe it's psychological....I dunno....but I wouldn't be afraid to wakeboarding on my buddy's boat with my full cap with a blue liner/ white glue attachment. I might wear my longer piece just because I don't want to take the chance of having a bit of lace lift at the hairline while I'm on the water, but as far as the overall integrity of the attachment, I wouldn't think twice about it.
