On one of my bikes I have a CX1 and would like to try a Rotor Q-Ring. Any experience ?

question #2: I'm using 44T on my Sram crank. If I for a Q-Ring should I lower the teeth and got for a 42T ?

No personal experience, but no front shifting probably is the best use of an asymmetric ring!

New Qcx1 rings are coming out with narrow wide teeth, that would be your best bet

yes I'm talking about the QCX1 which is already available here. The big question is I'm not sure whether I have to go for a Q-Ring 44T or 42T
I use 44T normal chainring and sometimes (deep mud/sand) 44T is beyond the limit of my legs' power.
I'm afraid the QRing 44T feels almost like a 46T while pushing (it's almost like a 42T on the dead spot)... so not sure yet I go for 44 or 42

Generally you replace the regular ring with a Qring of the same size. The power stroke is effectively larger, but due to the smaller non-power side, the pedaling force is supposed to be equal to the standard ring size. So if you run a 44T now, use a 44T Qring.
I have used Qrings and am now riding Osymetrics on the road. I used a single Qring for CX last year (haven't pulled the trigger on using them this year as I am on the new Ultegra 4-bolt and they don't do a CX ring-set for those yet)

Some of my teammates have tried them this summer in training and weren't happy with the setup.
They ran Dura-Ace DI2 derailleurs and after riding 30 minutes in muddy conditions, the chain started to drop

I'm running Dura Ace 9000 with 11-28 and 40t single ring on my disk bikes this year. I've yet to drop the chain on the QCX1 rings but havent ridden in much mud. Doesn't drop bunnyhopping UCI height hurdles though

I bought it and seems I like it so far. The only thing that worries me a bit is that the chain tension on the bottom is not the same while pedaling.
I'm not sure whether this would make the chain easier to fall in deep mud if at all
