I have an neipa featuring Galaxy that I've brewed 6 times over the last two years with the latest 10 gallon batch just this week. Love that one.
Also, did my first neipa with Idaho 7 three weeks ago. Should be conditioned by now, just waiting on a different keg to kick so I can swap in two freshies at the same time.
The only reference I have for Idaho is Sierra Nevada's Fantastic Haze which I thought was indeed a fantastic hazy brew...
I think Galaxy is the easy choice should be killer with the other two. If you want to go out of the box Idaho-7 could be really interesting. I would go Idaho-7 for no better reason than I have 1lb of that in my freezer
I don't think one could make a bad decision here I love Galaxy (probably more than most folks) and everything I've read about Idaho 7 has been highly complementary (fingers crossed, I'll know myself in a day or two)...
Subbed, I also have 8oz of Idaho 7 in my freezer that I haven't decided what to do with yet (wonderful husband read my mind and bought some with last flash sale at YVH). I'm considering pairing it with Mosaic and El Dorado, the ED for bittering and the Mosaic/Idaho 7 as late/dry hop additions on a two-row/light munich base.
Both with work. Idaho 7 will accentuate orange notes when paired with Amarillo and Citra. Galaxy will bring a tropical punch with those two. Also, Galaxy/Amarillo is most likely the hop combo in Tree house - Green
