I've NEVER used an expandable head. I like to keep things simple!
As a matter of fact, I'm going to REALLY keep things simple by just using my field points. You know, they fly just like....... well, field points!
Since 1995, I've been using Wasp SST Hammers. Beautiful broadheads. I can't see fixing something that ain't broke.
They worked great on my turkey as well, very durable.
