As others have mentioned, 1.8g is on the very top end of the recommended VTF range. And VTF on these is pretty particular, like a couple hundredths of a gram making an audible difference.
I'd slack it off to 1.7g and work towards the recommended 1.75g. Mine was happiest at 1.735g on the VPI 10.5i arm, and I can heartily recommend that combo if you decide to go that way. But I'd take a little VTF off it first.
