fishon01, With the single cam Patriot, module #PAT3 set at the 8.5 mark is for 65% at 27" draw.
The Pat#3 module set at the 7.5 mark will make the bow 28" draw at 80% let off.
If you' re looking for 28" and 65% let off, try putting a PAT#2 module in and set it on the 7.2 mark.
When settings the draw stop, start counting from the bottom (L) of the cam and count the marks up.
