I've beat the drum on this problem before, partially because I have the same issue: the beers I like are hoppy, just not as hoppy as they should be.
Great Divide is a particular culprit, using a bottling date without labeling it as such, therefore if you think it's a best before dates, the beer ends up 3 or 4 months older than you think it is. I've seen "Fresh" Hop on the shelves with 1+ year on it; at that stage, why bother?
This might help:

I recommend SN Celebration, whose hoppiness seems to hold up remarkably well.
