Hey, I am trying to make plans for my brewclub to come to my hop yard and brew up a Harvest Ale this fall. (after THEY pick all the hops we will need

) I have Centennial, Cascade, Chinook, Willamette, Magnum, and Nugget. We have discussed brewing an American IPA, maybe a IIPA, 50 to 70 gallons.
Any suggestions would be greatly appreciated.
Thanks,
hari
