You got your first post in while I was still writing.
This was perfect for the Hitachi with the left side mounted slide switch. Puts it right up front. Not sure how ergonomic a paddle switch one would be. I see the top mounted HF switch has finger room, but isn't ideal. I read where someone used a HF plugin foot switch to make it super quick and easy to use.
I did have to offset mine a little because of where the Hitachi spindle lock button is.
