25 knots 3-4m swell. I'd assume that is not your regular type conditions but one of those epic days ? Just saying you shouldn't be moving to a setup to initially cover that surely? Maybe it is normal ?
Hillys recommendations are sound. Start with the 1250 and then if need be build a quiver if need be around that.
I had my first crack on exactly the same setup the other day, 20-25 knots on a 5m unit wing (which has a powerful bottom end but large blow back near its top) and at 80kg I was well cooked wing wing size. The far more experienced guys including Jason (who came second in the recent King of the cut race) from WA surf were on 4m's. So not the ideal conditions for a first crack and even Jason was expecting some adjustment period on the Armstrong for the first run
But this was not the case. Straight up and all good all the way down.
To be honest it felt similar to the axis 900 (ultra short fuse setup) so the only adjustment was the much smaller 232 back wing. But that didn't take long and after a short time I was dialed in. As I said it felt very similar to the 900 just way more glide, far easier to pump without wing power to get to and ride the next swell line. Far more balanced, far smoother, coukd turn much harder without tip breach . well just superior in every sense to be frank. I didn't breach once in the entire session.
Also I opened up the tap a few times and the speed was ... scary at first but you quickly adjust due to the balance and predictability of the wing. Did bite off more than I could chew once and the crash made my ears ring a bit.
but it could also be ridden slow if one chose (which I mainly did as I was well over powered and there was swell running to), and had a remarkabley slow stall speed .. although that could be the extra glide in action.
now having said all that I have heard good things about the axis 980 etc to so maybe worth trying first who knows.
but if you go Armstrong hillys suggestion is bang on from what I just experienced. Very happy indeed

hope that helps.
