What FFL Should I Buy Next?

I've gone in and gotten the Nov Mu v2 (fossil gray MAO) in FFL351 1800k, the X1Q Core in FFL707A 4000K rosy, and an ~~X4Q~~ **X4** Stellar in 3700k/4000k FFL351 mix.

What should I look for now, to fill a hole on my collection? I've been eyeing the X1L in XHP 70.3 HI on 4500k, the E04 with MAO, or maybe an E07X v2.
