I learned on the same jp funster 145. I'm 82kg and was planing, footstraps and waterstarting. I got 2 new boards after moving the funster on recently. A jp slalom 112 and a tabou 3s 96. Can rip around on both fine. I love the jp slalom board and can make jybes most of the time, uphaul ok on it and go reely fast

The tabou is great but I defanitely struggle a bit more with it. Can sail it fine but make a lot less turns than on the jp. I can still uphaul on this board as well (just to see if I could) though it is a bit tricky it can be donr regularly with s bit of practice.
Hope this helps.
