Have never had the original, but I believe the beer that took out BABBs American Ale Mini-comp last year was a clone of this. It scored 44/50, and I did get a taste and it was astoundingly good.
Maybe you just need to 'adjust' to IPA bitterness levels. They certainly are full on if, for example, you class a beer like LCPA as 'bitter'...
Mind you, I'm very much keen to grab a bottle or six of this from Archive for the weekend......
Cheers!
