Is anybody using these or have tried them?.......just need your input and/or experience......
planning on trying them out!!

I currently shoot GT7595,5575,3555 for my different bows, just want to try something different....

Yepper I have and love them just as much as my Gold Tips. Gold Tip bought them several months back and I'm waiting to see some changes, all for the better.

Blackhawk Vapor Pro Series 4000's worked for me. For variety sake, I just got some Gold Tip XTs, I don't notice any POI difference. Both shafts seem to work well for me.

Blackhawk Vapor Pro Series 4000's work for me too . They fly real well and I have not had any problems with them !

Yep, the 5000's have worked great for me for 4 years now. I'm still shooting some that are 3&4 years old with 1000's of shots on them, and they're hitting with the newer shafts. So if they wear-out, I haven't seen it yet.
