I have a DID from MMV also, however... the positive capture on it is thumbscrews, which I've not had the best time with. Two of my gennies have them, and they have caused me trouble on both with ohms creeping up and not just a little either.
The RSST has a spring-loaded capture that is far easier to use, and never gave me any problems, but if one was to move past the RSST, I cannot find any fault with the Kraken.
