Chuck the mountech.
Really nice rd but you need to keep the upper jockey wheel really clean - they are known to blow up and replacements are not available on the road. Same issue with the knuckle - gets real dirty and the coil spring can snap.
I went down down the mountech superbetech road and ended up with a handful of extra arts just in case. You can have them for a song if you want to stay with the mountech.
Cyclone 2 gt would be my recommendation or a shimano mt-60
