    New rear derailleur needed...

    I currently have my S-works CX set up with a single front 42 and a rear 12-27 cassette with an ultegra med cage (broken due to locked pulley). I would like to get some more range because I want to keep it single up front, so I want to switch to an XT 11-34 and a single 44 front. My question is should I go with a long cage XTR M952 ($95) or with a long cage XT M750 ($57) or a med cage XT M760 (newest xt model) ($70). These are the options I can currently find to purchase in terms of price/performance. I don't know if the shifting advantage of a med cage outweighs the range advantage of a long cage. Is long cage for cyclocross just a bad idea?

    the problem with a long cage is the shifting is slower and the chain is longer. i'm not sure it's necessarily a bad idea, but i wonder if running that extra length of chain, as well as the looser spring in the rd might make for sloppy shifting in sloppy conditions. i do know that the rage among mountain bike racers in these parts is for a road rd on a road cassette for quicker shifting. my guess is that, with a single 44t chain ring up front, you probably won't need the extra chain length a long cage will give you, even with the wide-range cassette.
    when walking, just walk. when sitting, just sit. when riding, just ride. above all, don't wobble.

    Ive got a similiar set up. a 12-30 and a single 42 chain ring. I run an xt long cage with a single ultegra bar con. In index mode it does not run to well but friction mode works great. I have not been able to figure that one out? But with a 34 on the cassette I think youl need a long cage, anyone else on that???

    After all the input, I'm leaning heavy toward that setup. I'm still confused about why shimano would sacrifice strength with the xtr just to shave 50 grams. I can see using a lighter material/same strenght, but I'm a little in doubt that they would reduce durability for that small weight savings. Everyone is screaming XT at me tho, and I really appreciate the opinions.

    Well, I found a real deal at supergo and bought an xt 11-34 for $40 and I couldn't resist the XTR M952 Long cage for $89... And if I want to go with a triple front, I've got that option...
