Alright, I just finished playing with my bow and here' s what I' ve got.
The original module is a BT2 for 29" draw. I couldn' t ajdust the peg enough to get the 29.5" out of it. I don' t think I' m really getting 29" to be truthful.
So I put the new 30" mod on, moved the peg to the desired 80% letoff location and began to shoot. The chrono registered a solid 9 fps gain
. But the letoff felt terrible, like it was on the edge of the valley. Any creep foreward and it would try to leap forewards on me[:' (]. It was definately a lot closer to 29.5" though as my 28 3/8" arrow was behind the back edge of the riser at full draw.
Then I figured out what MAY be my problem. The 30" module my dealer sold me says DS1 on it.
If the original mod is a BT2, shouldn' t the 30" mod be a BT1 and not a DS1????
