After thinking about it, I suspect Hero needs a wider limping range at the expense of his raising range.
But I could be persuaded otherwise
I think your logic is sound... much depends on how wide the PF range is on your likely callers. And although it sounds pretty broad, the other thing in your favor is their relatively passivity PF. Otherwise, you'd have to fear being raised by an even better hand, PF, which you don't want - making you put in even more money while behind, and potentially dropping some of the caller that you want to build you pot in case you flop huge. Either way, you're still folding most flops.
