That's a nice sail for sure. Fun kite!

25 grams is the recommended tailweight in the plan. I like yoyo's to be slower and controllable but if one likes rolling up faster they might experiment with a bit more.
@clifford
Maybe try adding 1 or 2 grams, it makes a big difference. Also try to have the weight to end of the tail as much as possible. If you use a long brass rod inside the spine it also changes the balance because of the weight distribution.
