I recently came across some information regarding rotary backplate adapters dual action polishers. What are the benefits to using rotary back plates on a DA? What are the differences between the two, if any?
 
The main thing would be the use of smaller backing plates. There are smaller rotary backing plates available than for DA.
 
The main reason has been mentioned above.

Using a rotary back plate will also allow for some heat dissipation because the adapter itself will absorb some heat that is generated by the DA. DA can get quite hot and this heat travels down into the back plate and pads. Sometimes this causes delamination of the velcro or collapse of the foam pad center. (usually the heat is caused user error for working with dirty pad or too large of an area)

Rotary back plates have much larger threads and therefore much stronger. The extra strength is needed to safely spin a 8,9, and even 10 inch wool wad.

So you will see plenty of rotary back plate to DA adapters, but not the other way around. The 5/16" x 24 DA threads would not be safe on rotary.

If you decide to use the adapter, make sure that your BP and adapters
are snug.

I decided to stick with one type of thread this way I am not buying different backing plates for different machines. There are many rotary choices out there and the rotary backing plates on the DA do seem to run cooler, this can be important if you are using MF systems which are not heat friendy. You can also run the Optimum adapter that extends the backing plate outward thus giving you more reach on tight areas.

Here is a pick of my PC with the adapter on it. I currently use the Flex backing plate on it.

Another great benefit to using rotary backing plate on a day polished is the spacing. When using a mf bonnet, the edges will not shred like when running with the oe backing plate.
 
Do the quick connect systems work as stable, or as reliable?

I've been using the Edge 2000 quick disconnect system on both rotary and DA for a few years and they work well with both types of polishers. I assume that's what you're asking about.
 
which do you think will be less tippy on a gg6?

2.75 in rotary bp and DA adapter
or
3.5 in LC flexible bp?

I have both and don't like them on a DA. I have the 3" Griot's on my Christmas list and if I don't get I will just buy it.
