Seems noone's answering the phone at the Catsailor store, so maybe someone here can give me a quick answer on this - I need a set of wheels for a Blade F16. Cat Trax apparently come in two sizes 8' and 8.5'. The Blade is 8' 2". Which model do I want? The bigger or the smaller? Does it make any difference? I presume the cradle location on the axle is adjustable, yes?

Incidentally, Cat Trax seem to be in short supply. My local dealer, Hedlund Marine, have been out of stock for a couple of weeks and say the manufacturer can't supply them with any more until at least the first week of September.

Mark.
