Are you guys too "young" - so you havent been riding 20-26m2 kites, which was "cool" back in the days ?
I can tell you then, that you WONT get much out of it, sending these in 25 knots.
You can jump much higher with a smaller kite, as simple as that
If you somehow manage to get up high, you will have great hangtime though - but you will most likely not be able to get up there in the first place
These sizes became obsolete very fast, and even today bigger than 15-17 are not really used by anyone (medium sized)
