My actual draw weight before I started changing things was 34 lbs & I am using Platinum XX75's which will get to 80 yds and if they go in the right direction will stick inthe boss. It started with not being able to set the sight low enough (it's a cartel 2000 or something similar) and having to aim at a point in the trees just above the target but that's difficult to do right, especially with a short setting on the sight. I thought that moving the anchor a bit lower would help (moving my eye higher would also have worked but that's a bit extreme

)
The added benefit of extra draw length was something I didn't expect but which seems like a good thing and I would like to keep it if I can.
The platform is actually only about 8mm above my index finger and I could fill the gap with something - I'm not sure it would help.
