I've owned z avengers (overstable) and X avenger (dead straight when new but beat in way too quickly) and I'm looking for something right in between the 2. Can anyone tell which color ESP avenger is the most evenly stable?

Not sure about that but my orange one is very overstable.

i use all three, and believe you will find the ESP version smack dab between the X and the Z

i use the really light weight 164-167 esp for real long sweeping hyzers and some types of drives

hope this helps

My ESP Avenger is every bit as overstable as my Z. It is white 175g.

I had a few white ESP avengers (Sun King Ghost Stamped) that were around 166g and they were every bit as stable, if not more stable, than my Z Avengers. Too stable for what I wanted it for.

i could that happening at a 175 weight. i just dont have any of those heavier ones yet
