My attys sit flush. I mainly use Aromamizer Supremes but have also had a Billow V2, Billow V3 Plus, and Griffin 25mm on them.
Funny thing happened, no it's not fixed...
Got the Bachelor base and attached VT75 top plate out of the freezer and managed to separate them. Cranked that beyatch back on the VT tight.
Swapping between the VTs, I put the 'Mizer on the 75 and the Bachelor on the 133.
And it sits flush... or near enough as makes no never mind.
Thinking maybe I had just powered through rough threading (cold hardened threads? ) I pulled the B and started re-testing all of the others.
No joy.
Opened a VNW ticket a while ago, I should check my mail.
Can't return before Monday at the earliest so I'll have it for a few days minimum.
Just glad it's looking (fingers crossed) like I won't have to return both.
