Cabela's Expandable broadheads.
 

I dont know if any of you all have ever tried these out or not, but I have been using them for several years now and they have worked well for me. They are basically very similar to the older style Spitfires, but half the price. They fly great for my Xbow and just thought I would give them a plug as I know a lot of guys are affected by the economy like I am and can use a break in these high costs for equipment. Check them out as they sure do put a nice hole in 'em. The cutting diameter may not be what some of the newer heads have, but I like the chisel tip and if you put 'em in the breadbasket they do the job. Just took a 120lbs. doe on Sat. and she did not go more than thirty yards.
