I'm 10 kg heavier than you. My quiver isrobinsonpr wrote: ↑Mon Dec 11, 2017 12:05 am...I currently ride Slingshot Rallys (2014). I am now on a strapless surfboard and although the Rally seems pretty ok for my level and ability I am thinking of selling them and getting wave kites. I'm 75kg. Was thinking of the SST as I already ride Slingshot and like the quality. ... My Rally quiver is 7/9/12. Should I replace these with same sizings...
6 RPM, 8 SST, 10 SST, 12 Rally.
I'd keep your 12 Rally for light days. I haven't heard as much about the 12 SST as the other sizes, but I think your Rally will still give you the low end you like. And, when you want those nice gliding jumps it'll be welcomed. That said, you're lighter. 12 SST may be all you need.
All your small kites could be SSTs, in my case, I had the 6M RPM and it doesn't get much use so I kept it.
They didn't have all the small odd numbered sizes when I got on the kites so I didn't have a 7/9/12 option. My only question would be to make sure the jump from 9 SST to 12 Rally isn't too big. I don't like flying my 12 over 20mph... so you have to see how early you can step onto the 9.
