I havent had the chance to mess around with any lupomax hops yet. I read up on them a little bit and it definitely sounds like a guy could end up hooked on using them over T90 in a lot of instances. I have a little bit of lupomax el dorado that I have planned in a different IPA ( coincidently using this recipe, just tweaking the hop additions for using multiple varieties) and am kinda excited for it.
