I don't know for sure what gauge Rog is more confident with, y'know it only said that it was the right brand, but to know the exact gauge you'd have to ask someone who works with him, the guy in his fave instruments shop or himself!
Anyway I seem to remember the ones I bought had the G of a good 46 and they sound great.
Remember that Rog usually works with 2 basses (at least on stage, I assume him to own many more), one with standard tuning and the other on a drop-D tuning, which means that you have to get your low E tuned down to a D, as heard a lot on the wall (The Happiest Days of Our Lives, ABITW 2 & 3, What Shall We Do Now, Run Like Hell etc), so for that tuned down E string I'd suggest a custom, thicker gauge.
