I voted expandables for one reason, the vitals are so small I shoot expandables for every game that i hunt, mainly because i have confidence in the heads that i use and have had great success w/ them.
Brad, i carried the Rage 2 blade for deer last year, and Snypers. Last spring for turkey season, i carried the Sidewinders and Snypers but i had a Sidewinder on b/c of the cutting diameter and im able to shoot through the mesh. Bottom line for me was that if i missed a gobbler b/c of flight, i would go to a Snyper for a possible second shot b/c i know how they fly, and im confident in them
