Rocket Ron Protections are a good balance of speed and grip. Not very different from X kings though. I've not tried Ralphs on a 29er but they might work better than on a 26er where I found them rear only and sketchy on anything not bone dry. Also not tried Thunderburts.
I'd go protection version every time. Actually I think X kings in black chilli are as good as Rons and probably what I am moving to as I've had a lot of training punctures on Rons. Your pressures do sound a bit low but weight, carcass strength, line choice and rims are all factors
BTW there is an internet legend that Contis come with mould release agent on the side walls that interferes with latex sealing. Supposedly if you wipe the inside down with alcohol or similar it helps the sidewalls seal.

Much better race today at deep cut.
A course that suited both the bike and myself, some elevation gain and no real features to cause bottle necks on the first lap. Dropped a category and managed fifth in sport - kind of wanted to do another lap.
Rode with a bit more pressure (22/28), mostly because I'm still losing a bit of air from the rear tyre, and it seemed okay, bit of finger pain but nothing I couldn't deal with.

I find Rons the least grippy - but probably fastest in a straight line - of all the schwalbe knobbly MTB line up.

So much overlap in mountain bike fields, but I suppose it's necessary when you've got that many people racing.
Continental X-Kings: 2.4" front and 2.2" rear. They've been okay (good for £15 a tyre) but the sidewalls are too thin to seal up tubeless properly. I've been running 18 psi in the front and 22 psi in the rear without any punctures thus far. I suppose 2.4" lightweight XC tyres are few and far between. Schwalbe looks like the best option thus far, most of their all-round offerings go up to 2.35", get decent reviews and seal up well.
