Rode both the 1250 and 1125 in 20-30 knots. A local Armstrong rep let me borrow the 1125, and today had perfect conditions to wing and do side by side testing. Both foils rode fast. The 1250 is easier to carve rail to rail. The 1125 was a little faster and had more glide. I can definitely see its utility for downwind runs. The 1125 felt really smooth cutting through chop, and was surprised me by how little power was needed to keep it going. I was constantly spilling wind trying to get a stall, but it easily milked the wave power. This felt completely different from the 1250. So the increased efficiency really stood out. Unfortunately while exiting the beach, I hit a rock

just before getting to stomach deep water. It left a noticeable gouge so I guess I'll have to buy the 1125 and do some wet sanding. At least I got to try beforehand.
