Have a look at the board showcase on
kenalu.com/ they have reviews on most of the Jimmy Lewis boards. I am 100kg have been SUPing for about 8 months on a Naish 11'6", no surfing background. I recently paddled a JL 10'8" Surf on flat water and I could possibly surf one now, but it would of been too small for me to start on. I also tried the 11'2" Starboard and think you could probably start with that, Kenalu has a review and so does Starboard on their SUP forum
www.star-board.com/.I use the same paddle for surf and flat water, cut to flat water length. Some people like to have a surf paddle a couple of inches shorter. I have a Werner paddle and I love it, it is light and strong. The only other paddle I have tried is the cheap Naish, I couldn't recommend it, it's very heavy, probably too short and won't be strong enough for you in the surf.
