It's a small and very soft fin that softens up the ride quite a lot compared tot the original 22 and also compared to many other wave fins.
Upwind is fine, no problem. I generally use a Wardog High Wind 22 for 4.2-5.3 and switch to the Drake 22 with the 3.7. The drake is much softer and helps, but you are right trying a Drake 20 might be a good idea, also considering that we see maybe 5-7 days of 3.7 each year ... (one of which today, that I am missing due to a stupid out of the blue muscle spasm in my back!!!!)
