More important than picking a heavier rod is learning to haul and double haul.
+1. Any rod 7-10 weight would work fine provided that your casting is good.
Good casting trumps rod weight, line weight, overlining or underlining, etc.
I agree with Rip about accuracy >> distance for bass. I don't care for bass taper lines (or any extreme weight forward types) but they do well for huge bugs at short distances of 20-50'. Anything over that and I prefer a more typical WF line.
