It is amazing how much difference the little things can help.
A change with the release works sometimes and I actually modified my Mongoose to work for me.A loop sounds like it might be just the thing for you.
Don' t be afraid to experiment but when you make changes,make them 1 at a time so you know if the change is working or not.
A module shouldn' t change nock height but will most likely require a longer stiffer arrow.
