I have been using expandables since I restarted bow hunting 3 years ago. I am aware that the advantage to expandables is suppose to be improved flight and longer range accuracy versus fixed broadheads. I also realize that fixed broadheads have better pentration. What are other pros and cons of each, as I am debating going to fixed broadheads. Thanks ahead of time.

That about says it. I use fixed blades for the simplicity/toughness issue. There's nothing that can go wrong. If you tune them correctly, you can get excellent accuracy from fixed blades. I can shoot almost as well with my Thunderheads as with my field points. Thunderheads or Muzzy's are my broadhead of choice. You won't go wrong with them.
