Bill, I have the trend pro and it works well but I find it uncomfortable and do not use it regularly unless sanding a lot.
I use the same face shield you do and run my dust collection normally when turning. Easier on my neck and back.
there are other systems like the trend, all are expensive. I would like to try before I buy. You could try mine and maybe other club members with a different type would let you try theirs.
