I know what you mean about having a bishop always on g2 and how that can get tiresome.
I can relate: in the Catalan, my favorite memories are from the times when I was able to shift my bishop to e4 and start a raging attack with Qg4(h5), Ng5, Kg2, Rh1, h4, h5, etc...
Actually, I had similar feelings with black after having played so many Grunfelds, Closed Sicilians, GP Attacks, etc. In the Modern Benoni, I always had an eye out for the moment when I could point my bishop at the white king with Bd4(+) after a weakening f3 or f4.
When I started playing the QGA and Meran systems, I almost wept for joy
when I realised how often I could point BOTH bishops at the white king by Bb7 and Bd6(c5). Of course this was the result of inaccurate play by white, but it happens more often than one might think!
Good luck pointing your bishops at your opponent's king (in whatever way you can!)
