Are you in the US? American IPAs are quite different from British or other European IPAs in style and flavour. Could be worth trying if you can find some as the British IPAs tend to be much less heavy on the bitter notes and have a rounder flavour.
I am more positively inclined to British beers like Spitfire and Bishop's Finger which, although I'm not sure they're technically IPA, are definitely quite bitter. I don't think I've ever seen them in the US, though.
