This is a little late because I just found this site. I just fitted a Masterclass e-way buttplate on a Rirchards Microfit stock. Alex Sitman has been great to work with. He sent me the DV 4- and the Masterclass 3-way to evaluate. He said, "just send the one you don't use back to me."
I opted for the Masterclass because the DV was clearly designed for small-bore, and I didn't think it would stay tight with any real recoil. I had orginally ordered the Tubb 4-way, but after three weeks of hearing that McMillon would be shipping them any day now, I decided to cancel the order. I would still like to have the 4-way, but I am very pleased with what I got.
