I find on target gives alot of combos as too stiff, when I find them just right.

I have put my faith into Ontarget a few times only to find out I had too weak an arrow.

Same thing happened to me recently with my PSE Mohave with medium wheels set at 67#. Said my beman 400's were fine, but I had to move up to .340s.

It calls my currently liberty setup with carbon express Edge's 350's too stiff, but I had to move from 125gr tips to 100's.
