With the amount of gear Dracop handles, he has a great grasp of what is out there kite wise. I would listen to his advice.
As for my own opinion, I would suggest a Best TS as an option for you, but probably a 10m. I have a 12m and a 9m and weigh 85kg. I can use the 12m starting at 15 knots, and by 25 knots it is too much. I have not had the chance to take the 9m above 30 knots yet, but it had plenty of depower left. I can start to use the 9m around 20 knots. I also have a 10m Roca, and it has the same high end at the 12m TS, and a bit more low end. I think the Roca is more representative of the average kite from a size perspective, while the TS seems to need bigger kites than average. If you cannot find a TS, look for the Eleveight FS.
Eleveight FS is way better than the Best TS, better at looping for sure!
