    Chainrings, light vs. Stiff? TA Chinook, RF turbine or XT?

    I see that some people stick with or choose XX rings on their setups for their shifting performance even though they are rather heavy. Does ring stiffness affect shifting performance? Do lightweight rings flex and result in bad shifting or is it mostly ramp design?

    I just got new crank arms (raceface next SL 3X) and am looking for rings to put on it. I previously tried TA specialites chinook 40t,26t combo on some m970 xtr and I could never get them to shift well, might have been because the spacing wasn't perfect or maybe the ring size gap was to big, or the derailleurs I tried weren't up to the task (XTR and a DA).

    I want a 24t,36t 64/104bcd combo (this is for a 29er) and can't decide if I should give the specialites another shot or try something different and heavier like the RF turbine rings, or something tried and true like the 36t XT M771/M761 rings? The xt M761 36t rings worked really well on my last xtr 29er setup, and my all mountain bike with RF cranks.
    any other rings I should look at for lightweight and good performance?
