I've recently been running a Minion DHF 70a single ply tyre on the rear and found the thread to be really grippy compared to the RQ.
However when it came to pinching, I found the DHF to be a lot worse. It's probably worth mentioning that both tyres weigh almost exactly the same. The difference is that where the DHF's weight comes from the metal wire, the RQ's weight comes from it having a lot more rubber which forms a protective layer. So although it's not difficult to pinch a RQ, I'd say it's pretty good for such a light tyre.
I agree with there being a lot of roll but the bounce is insanely good. Also recently after installing a Maxxis Freeride tube (300g) I've had no pinches at all on the RQ. Personally I think you'll get more protection from using a Rubber Queen and a thick inner tube then from a 200g heavier tyre but 200g lighter tube.
About the front tyre, I'm having more issues with it recently whereas if I do a big gap to front, the tyre will push into the rim. The only way to pull it out is to deflate.
