You can adjust the bridle to the top knot, but you may then also need to adjust the bridle a bit. Has Lam ever showed you the trick of then ensuring that the bridle is where it should be? I can make a vid of it at some point - easy to show and do, hard to explain.
I adjusted my SUL so it pulls more that way, but I am not sure it really affects the low end.
I fly my standard in pretty low winds (for a standard) with no adjustments at all - 3 mph.
Fearless Light US is a smaller size APA than what is on the standard. I think the FVL uses the larger APA.
The video would be helpful.
