I think the chop lines are more of a marketing ploy as they added them after it became trendy to chop your stab. People are chopping everything to get more performance.
In my opinion people think they can just jump on the HA1125 and rip but it's just not the case. It has a learning curve even for experienced foilers and I believe people are giving up on it too soon. I also didn't like the HA1125 at first but it has become my favourite foil.
The opinion I've gathered from all these videos is the new HA925 is friendlier and doesn't have the learning curve of the HA1125.
Time will tell but I think I need this wing
