Pinnella really brought it all together on this last album; his tone and phrasing are much better than in previous albums. Pinnela's solos on "Inferno", "Wicked", "The Turning", and "The Odyssey" (during pt. 2 around 8:00) are absolutely amazing, in fact I've found myself fast-forwarding through Romeo solos to get to Pinnella solos lately.
In addition to the solos I listed above, I also appreciate Romeo's work on "Out of the Ashes", "King of Terrors", and "Inferno" (the tapping one and the one in-between the verses). I also like the duel on "Smoke and Mirrors".
