Here's my take. Realize this is coming from a 67 year old who started bow hunting in 1962. Like a lot of old dudes, I do not fix what ain't broke. However after a signioficant injury several years back I switched to a Cross Bow. I have no averse position to expandables, however I have used fixed blades for 50+ yeaars with excellent results on both penetration and quick kills. I would suggest you try a fixed blade. Check with Excaliber for advice on total bolt/broad head weight. If OK, try something like a 125 gr., 3-blade. I use the Montec brand. I have used Muzzy and Thunderhead 3-blade boradheads. Not one single issue with flight or penetration or quick kills. My Cross Bow is a Parker Tornado that is now 4 years old. I use 20" Red Hot bolts and a 125 Gr. Montec one piece 3 blade. Deadly combination for sure.

Good luck and hope "the big one' eases by you this season.
