Pretty much spot on here. I used them a lot more when I first got the III, but now I find them quite dark. I remember liking one of them after resetting the amp in beta firmware 27. However, I use the Friedman dynacabs on almost every preset. I mix a Friedman GB with a Friedman V30. 60% of the time, it works every time.
The Splawns are a bit tricky to dial in as they're either overly compressed and bass heavy (Nitro), or just have some odd pot values that make them unintuitive to use (Quickrod). I find the Cameron's to be a good middle ground. Bogner's can be a bit tricky to dial in as well, but I always seem to remember that the amp works well with extreme settings.
