Why not go back to Mesa Rectifiers as you already know it works for you? Getting something blind to see if it works for you is quite a gamble as it could be a waste of time and money if you find it isn't entirely for you. Having said that, you've owned a Tverb and I remember reading a post that you loved a Series 2 ROVERB. Perhaps try a Roadster at a local shop and make a decision based on that? IMO theres no reason to look for something else if you've been happy enough with the Rectifier Series.
