To be candid about it, I don't use ANY handle on any of my D/A buffers at home. I've got a couple each of the 7424 and G110 so I have handle choices. I don't bother with them at all, instead I just grab hold of the head of the machine and work it that way. I do use a stick handle on my Makita rotary though. Oddly enough, the Porter Cable rotary I had came with a "D" handle and I didn't care for it on that machine. Of course, that machine died after using it half a dozen times so..............
