Honestly, don't waste your time with Phantasm. The flavor is far more subtle than the hops you'll be using, and it just ends up getting lost.
I like IPAs with huge hop flavor like a NEIPA, but with a firm bitterness like a West Coast. Grain bill is usually 95% Pale/Pils/Vienna base and 5% Crystal malt (20-60L depending on my mood). I bitter to 70ish IBU with Columbus or Chinook, and then use mostly cryo hops ( a lot - 1-2 oz/gallon) at flameout/whirlpool, and then again for dry hops. I generally use BRY-97 or Verdant IPA for my yeast.
Hop choice is where the fun comes in. I almost always use Citra for 1/4 to 1/2 of the hops for the high oil content and a base mango/citrus character, and then I stack on other varieties depending on what I'm looking for. There are so many varieties to play with, and you really can't go wrong with just about any combination.
