@ Henry: Yes it is the Juya one, and I also had the problem with the fabric bunching, but I found a solution for it quite quickly. All you have to do is, when your putting it on, you have the lower velcro more to the far side (Kinda like \ that) so it makes the fabric bunching flatten.
@ Mm: I'm probably something in the b-c range aswell, but I can't say for sure.
@ Everyone else: Thanks guys ^^
