Why do you want the 117? For speed and 20-25 knots, don't you need something smaller? The 107, 97 or 90 would seem like better choices, plus your JP is somewhat similar to the 117.
I don't know much about the differences between the 117's, but for speed and your 72kg, I would go for the iS 97 or even the iS 90.
Your 7.2 RS sail will be a little large on both the 97 and 90, but for speed in 20-25+ knots, you will do better with a 6.5. Plenty of power and much less drag.
I have an '08 iS 111 (similar to the new 107) and it is a bit large for me in 20-25 knots and I weigh 78kg. I use the board primarily for 15-20 knot winds and go to a smaller board in 20+ knots.
Just my thoughts........
Formula 160; iSonic 111; HiFly Move 105; Tiga 263; '85 Mistral Superlight.
Maui Sails TR 11.0; 9.2; 8.4; 7.6; 6.6; Maui Sails Switch 6.0; 5.2; Maui Sails Global 4.5; 4.0.
