Mathews TRX7 and TRX38

[brassgbits]

I have had the 7 for a few years now recently I acquired a 38 which as the same cam and module setup. The valley on the 38 is virtually none existent towards the 7.
apart from the shorter ATA I don’t know why it is so maybe a member can shed some light on the subject.
I intended using the bows for different types of archery but didn’t expect a noticeable difference Or learning curve.

The first thing to confirm would be if the cam and modules are in fact the same: mistakes happen, and different letoff modules would feel different. Then check the cam timing and rotation in case there is a slight difference there.
If all those come out identical then it would suggest there has been a small, unpublicised design change.
