You were litt and rode quite a while
I was watching you and Thomas Crawford down there.
I don't know, seems like a 15 and a 9m Ion might be the combo.
I literally had no problem holding the 15m down in 20 (it was easy with the kite depowered about 75%....., not even edging that hard). I think I could go 25.
The 15m Fusion was noticeably harder to hold down and my 16m RRD.. well.. that thing is a PIG in comparison...
