what are you using for tight spaces....are you just manhandling the rupes and making it work ....what do u feel is the better combo to go with the 21 .griots 6inch or griots 3inch the better companion
I have a Rupe 75 to fit that need. If for some reason I can't use my compressor then I use my PC XP or GG 6.
I dont have a 21 I have a 15 but for small areas and thin panels I use my Griots with 2.75" or 3.5" BP and 3-4" pads
