Hey Mike,
The Hi Gloss pads are a great option, but there are many choices depending on your preference or polishing style.
Each pad has its advantages as to why it may improve the polishing experience.
Hi gloss pads are nice because along with the CCS feature along with the softer density foam to tilt, angle or adjust the polisher while keeping more of the pad planted to the surface of the paint. The softer foam backing gives it a nice cushioned feel as well.
The hybrid line would work well, but I would suggest others before, only because the orange Hybrid pad can be very aggressive in a rotary application. ESPECIALLY for someone without a lot of experience behind a rotary.
The waffle pad has always been a popular choice for rotary use, and due to the pattern of the pad, keeps the working surface cooler rather than a flat pad typically.
Like I said before, a lot is personal preference so you may get a variety of opinions.
Some may disagree, but I personally like the 7.5" curved CCS pads on the 6" backing plate. The 7.5" pad is slightly smaller than a full size pad (around 6.5" backing on the pad), and provides the user a lot of maneuvering ability but still be precise.
I like them because when I'm using a rotary polisher, I am typically using angled in a "cutting" type position. With the slightly curved face, this gives you a larger contact area with out the added pressure from compressing a flat pad to curve on an angle.
Hope that may help a little, and I'm subscribed to see what everyone else likes to use on their PE's and rotary polishers in general

rops: Congrats on the new polisher. The PE14 is awesome!
