I just made a 10g batch, a whole-hop Apollo IPA, but with half of it dry-hopped with Apollo and the other half dry-hopped with Cascade. The hops are a year old, I picked them up from HopsDirect and forgot about them. The all Apollo has a notable apricot taste to it, not too far off from a Chinook but kinda more interesting if not complex, and nowhere near 'dank'. The one with Cascade is really well balanced on hop flavor; seems like a great match.
The house IPA hop schedule I'm working on does not to go for bitterness (45 IBU/1.070 OG) but is heavy towards the end with hop additions. Dry-hopped with 3.5 oz in each 5g.
The only hops I've had trouble with are Willamette pellets, they just kinda steadily went to that 'dirt' flavor over time. To your question, I'd rather stick with more predictable hops for the dry hop (Centennial, Cascade and so on), but love this one in the boil.
