Rob,
Someone like you who obviously knows how to use an orbital well will make the transistion without a problem. I remember when I came to Autopia, I had my Makita and I read so many posts about how rotary polishers are way more than you need and capable of doing such severe damage that I just let it sit....Now it's a different story.... I've been using my Makita for a few years without incident (I've actually owned it for a LONG time, just wasnt confident enough with it). Sometimes I finish with rotary, and sometimes I finish with PC. Depends on what product I'm using (some products I would rather use a PC for) I'm just a little more careful with it.
