Yeah
I actually like the clicker on my spig because it makes more of a "ping" sound than the click of a beiter. I just like it sounding different. Even if you're suppose to 'feel" the clicker.
In one way, yes, it really doesn't affect how the bow shoots. FPS doesn't change, nothing changed in terms of the bow and the arrow. Because the limbs start to rattle after the arrow has left the riser. however, as miles pointed out correctly, its a comfort factor. If you are more comfortable with a bow, you're more comfortable with a shot, and you'll shoot better.
I think Jim C. would probably say that those microvibs drive archers with bad wrists and elbows nuts.
