I've used the Kosmos on 2 butts now and have been very pleased with the results. In fact i just ordered some more of it today....... Good stuff!!! I definitely recommend it!
I used the 1/2 lb sample pack as well and soaked them for 2 days in a 2 gallon ziploc bag and then injected them with the soak liquid. One went in the UDS and the other went in the freezer. That one went in the UDS about a month later and both came out fantastic. Nice and juicy and full of flavor.
