Hello everyone, registered recently but been following the forum for some time

My question is; Is there any good rear derailleur for 10 speed system. Removed Ultegra 6600 from the bike, it needs rebuild and is scratched up, so i'm looking for a new rear derailleur that can work on Ultegra system, cable pull ratio is 1.7mm
Also prefer something lighter if posible with short cage.
My Ultegra is just above 200 grams.
