RE: OT2 and AA people...arrow help.
The ACC 3-49's are certainly not underspined for your set up. I've found some of the older model slick tricks wobble a bit on a spin test. Have you tested for this. Sometimes you interchange the blades and even 'changing' thewasher between the BH and the insert will correct this. I'm just searching for answers here, just areas to look at.
