Mike,
I shoot them and have for years. I like them a lot. Blood trails are awesome and they fly great. I usually don' t even have to move my sights for them from my field points. As a matter of fact, I was shooting them tonight, almost knocked one of those fancy, high dollar tracer nocks off.
I usually spend the couple of extra bucks and get the Pro Series. You know I' m working just up the road from Bass Pro shops, I could pick you up a set if you' d like. [:-]
