I have that DRO, except I used the 500mm size, on my Taig-based lathe on the Z (long) axis. It's ideal for setting the end of the ferrule to "0" and then taking only .001-.002" off for facing purposes. I have no problem with the size of the readout on mine.

I also have a Mike Gulyassy Sledgehammer Cue it was made in 2005 I've not tried jumping any balls with it yet but it spreads out the balls on the break very well , so in turn I feel it will do well jumping balls when I start trying that next after I get some cloth to protect the table .
