I like the super I have as well, and if I was doing sharpening as a business I'd have one, and sometimes I do
.
Just wish I had some way to disconnect the hydraulics from the clamp for the initial setup.
I used another tecomec with the wider wheel for rakers rather than removing wheels, same as I would advise for sharpening for $$$.
If your doing rakers with a grinder, which you'll want to do when guys bring you chains worn half way down that the rakers have never been touched on
, do not take them down all at once or they will harden and then a file won't take them down without ruining it.
