can't say much about POR as I haven't used it...but I brewed a pale ale extract beer recently with equal bittering from green bullet and super alpha (to 37 IBU's). It was a bit different, I guess when they say "resiny" that's what it tastes like, but it was kind of fruity, not unpleasant or over the top. I would do it again (just to use up the leftovers) and either drop the bittering back to 34 or add some crystal malt to help balance it a little more. (But the balance issue was my fault not the hops)
But I found it was pretty good in a no nonsence kind of way.
Hope that helps a bit.
