Product called Hyrdroturf is awesome. There is also another product that is similar being sold by SBT. There is currently a thread discussing them both.
I would say either the Hydroturf or the Blacktip mats are a great choice. Both have many color choices.
With any choice they do make a big difference in how your PWC will look
Nice thing about Hydroturf and Blacktip is that all of the mat sticks to the surface of the ski whereas the OEM mats are riveted and bulge upwards between rivets.
