More horizontial issues than anything. Technically, if your form is perfect, I mean perfect, and the your cams are perfectly square with the bow, and your rest is perfectly centered, it doesn't matter. And its 10X more critical for us finger shooters.

With that setup, you will be more likely trying to move the rest too far towards the riser.

Problem is none of us or our bows are perfect.

340's at 28" are way too stiff however. Not even close.
