It's not supposed to be tight, sounds just right to me.

 

You want a little room at the top of the arrow. Here is a size chart. http://1.bp.blogspot.com/_XJCwikq2v4o/TTivW9JvzbI/AAAAAAAABho/Wkx8xnqwkkQ/s1600/arrow-rest-guide.gif

 

The arrow should never be tight in the biscuit. It doesn't matter how loose it is, as long as it's not tight.

Think about a drop-away (or any other type of rest) , what you need is some support, not confinement.

As long as you make the draw and the shot the same for every shot, nothing else counts. It's all about consistency.

Now, go find something else to worry about. :wink:

 

Agree with the others, your over thinking it. Too tight would be huge problems.

 

I switched to the size small biscuit from the medium. Using .295" arrows. Didn't really notice much difference except the small us noticeably quiter drawing back.

 

Yup, as stated, supposed to be a little loose,
A friend of mine was using a WB that came with his bow, he was shooting I believe his old Aluminum XX75 or the like, they were too big for that rest and every time he drew back there was a faint screech. He has since switched to a smaller diameter arrow.
Only part of arrow that should be touching is bottom side, resting on the rest.

 

you would see basically the exact same thing with any other rest,, the arrow will flex at the shot,,, and some of those videos or very slanted in there purpose,,,, it is very simple to shoot an under spined arrow to create a "greater " visual effect..... if manufacturer x wants to prove his product is better than manufacturer Z all they need to do is tune the bow for their product and "untune " it for the other,,,, don't believe anything just because it is on video...

 

This is very true.

 

An arrow rebounds off the support provided on it's underside by any static rest on the shot. When matched with a decently spined shaft and tuned correctly the results are very consistent. Ever wonder why so many of us use blades for target archery? It is because of their simplicity, forgiveness and tunability. A whisker biscuit is a great containment static hunting rest with no moving parts. When matched correctly with size of the biscuit hole, the arrow shaft only contacts the bottom bristles of the biscuit. The rest is extremely accurate for any hunting application. A few years ago I shot a few groups on film at 100 yards to disprove the theory that a WB couldn't possibly be accurate beyond normal hunting ranges... A couple 3" groups proved otherwise. :wink:

 

wb is not supposed to be tight. follow the company's sizing recommendations.

"regular" sized carbons get a medium.
skinny carbons (fmj, axis, gt kinetics, etc) get a small.

 

op,i have installed hndreds of wb's and they usually tune well but i have seen where sometimes small shafts like victory vaps etc.,will not tune and you can call the factory to verify this. On a fall away, there is no vane contact,but on a wb the vane contact will force the shaft up into a "too large bisquit" creating a high tear etc.
