Thanks Cossack.

I might just add some small brass weights to the aluminium inserts to add a little weight up front will keeping 100gr tip, broadheads and the Judo.

I didn't know thats what bolts were... To me crossbows use arrows, just because it a couple of inches shorter the what bows use doesn't mean its any different, but it seems like some forums get offended when I say arrows for crossbow....
