I run mine ay 8.5 to 9.0 for color saturation. I love both machines. BUT I like the fact I can get different stroke lengths with the neo and the people at neo are AMAZING to work with and speak to.
BUT I haven't had any issues with either machine.
But like it was said, if you like the bishop I suggest trying a neo (maybe Med. stroke) and try it. If ya don't like it let ME know and I'll trade ya or buy it outright from ya.
Thanks,
Russ
