It takes a little getting use to in regards to the size (length). I had to move my C-clamp over about 4 inches to compensate between the Regal and the TRV.
I have a habit of resting my left hand on the vise, and last week it was the first time I noticed just how comfortable it was.
I have tied just over 10 dozen flies and one thing that I really like about it is that you don't have to clamp down hard on the hook for it to hold it securely. Rather surprising just how little pressure is needed.
Yesterday I was at a fly tying event while adding chenille it was the first time I used the rotary, it was SWEET...
I haven't found any where it is lacking.
I am very comfortable with the vise.
