With the season just around the corner I have been wondering if I should replace my blades on my NAP Spitfire XP Pro expandables or maybe move back to the fixed blade broadhead this year. It seems that fletching continues to improve and from what I can see broadheads of all types seem to be getting better. What type of broadheads are all of you using? I was just trying to get a feel for what seems to be working well right now. I can't complain at all about the XP Pro's but I thought I would check before spending money on replacement blades. Any thoughts?
