The Apollo I got from yvhops.com this year had a lot of that orange-citrus note that I get from Amarillo, but with some dank as well. I'd consider blending in some Cascade with it to get more of the flowery note I pick up from Amarillo as well. Maybe 2:1 of Apollo to Cascade.
Cents would be a decent 1:1 sub, but I get more lemon than orange from them.
