I haven't had FSDO at all. All my vibes have been rentals. Once they have been cleaned up and orings replaced,they shoot just fine. Actually like they just came out of the box.
Vibes just need some TLC. I only use stock boards (multi fire modes). I use either KILA or Orange detents. I have an Orange bolt in one of my Vibes and SP1 both work excellent for me.
I just built another Vibe with a used L7 bolt. I'll let you know how it works when I get it all together.
