If you are looking for ease of use and products designed for a dual action polisher you can't beat the Poorboy SSRs. Easy on, super easy off, very effective, won't dust (if you use it right) and the SSR2.5 / SSR1 combo is very hard to beat. SSR2.5 will handle medium to heavy swirls depending on the pad choice... and probably light swirls too with a finishing pad. SSR1 will boost up the shine from the 2.5 and you'll be ready for your LSP.
IMO Menzerna is a pain to work with via PC. I've used the IP, FP and PG and all three are very difficult to remove no matter what. But then again I am comparing them to the SSRs and XMT polishes... but with the rotary you can't beat Menzerna or Optimum.
