Im a 49 ogre who does not have time to fight in uber raids and such. A week or so ago i got (bought) me a pair of kylong leggs. I came across these this morning for 900pp.
Believe you me, I bought them and will put them on as soon as I can get them to my warrior.
the weight is a non issue to a warrior, as stated already. It might be a problem for a cleric, but they need wis and such (most anyway) instead of pure ac.
if you have better, im sure a quick check in DL or other lvl 50ish zone will give you many tells that would like them.
