I don' t know about 99% but I do really like my new LX at 80%. The new HP cam can be set at either 65% or 80% I tried both and am sticking with the 80%.

99% seems like there would be a huge hump in the bow yet my first bow at 50% was almost impossible to pull over the wall. My last bow was OK at 65%, but the LX is way smoother at 80%? If it is true that higher letoff has a larger wall to get over then why is my bow so darn smooth?

I don' t care who you are you can' t hold your arms at draw for very long regardless of let-off. Try this, put a large mug of boiling hot coffee filled to the rim at arms length, now just hold it there, a little longer, ohhhhh now it' s shaking, ok you just burned your hand.....
