[QUOTE=tackit;305551]To each his own but to me smaller rat tail grinders are the most controllable. Here is my Makita 6" rat tail grinder that Makita quit making. I have two Hitachi rat tails in 5" but I run 6" wheels on them too. IMO 6" rat tails are the perfect size for most open jobs.

I agree. I have a 5" DeWalt, and unless I am doing serious grinding, my 7" Milwaukee stays in the cabinet.
