I'm on a 1150 with 440 tail. Had a 400 first but my jibe success rate dropped to 20%. With the 440 i got back to 95%. On a tiny lake with gusty Winds. I guess it is a matter of experience and skill.
Time on the water and giving your muscle memory time to adapt to the different equipment.
Over 2 years, I went...
1020/440 standard fuse
1050/440/400 short fuse
1050/409/370/460HA crazy short fuse
1300/370/340 ultra crazy short
Changing the rear stab or fuse makes a huge difference.
