For at least the last year Mob sheets have been more rigid, and it's actually really hard not to get creases near the end of the nose or tail if the board has any concave within either (like all BBS decks etc). Think of it like trying to put a sticker on the inside of a bowl - it will crease somewhere because of the contoured surface. I work in a shop and it takes a lot of effort to do it right when it never used to. Plus, we've had people - including my friends - complain that when they got home their boards had formed creases in the grip. This has happened to my own set up a lot in the past year - the grip goes on fine, but in the morning a crease or two has popped up, and once they do, they never stay back down again. I know a brand manager at NHS and hit him up - he says they're aware of it but he's not sure what, if anything, is being done about it.
So, after years, I've switched back to Jessup. No issues so far.
