Building an SL and a couple questions so far.

What prop should I run for primary wakeboarding, some surfing, top speed not extremely important. The options on the builder;

ACME 3131 16x12.5

ACME 3591 16x13.9

ACME 3499 16x17


And, does anyone have close up of their interior handy? I am going to do pecan and light graphite. The dealer says the thread color is so subtle you can't see it. White is free for the seats and dash. $240 charge for all other colors on the dash and seats. Is it important to match the dash and seat threads to the interior colors?

Thanks, I may have a few more questions as I go. But, build date 7/13 and dealer wants the build at the latest by Monday.
