Thanks for all the good info fellas.I went to the local bow shop yesterday.Well dont let me near that joint with money in my pocket.I bought a whisker biscuit and fitted it straight away.After a dozen or so shots to make it shoot right and sights moved holy ****.I sunk an arrow fair up the ass of another arrow.I was shocked at first,then cranky because its a $12 arrow gone,but im pretty happy with the tighter groups its giving me.It did give me a chance to see just how tough the X weave arrows really are.Here some pics and video of the last couple days mucking around.
The whisker biscuit fitted

As it sat after the shot,nearly drove the first arrow through the back of the target.

Pulled out for a bit of a look.

Bloody hell

close up,It was hard to remove the other arrow too.
