The 055CXPRO3 are nice legs.
I started with an RC2 setup, the 496/498 heads do settle after locking, making precise positioning difficult. The RC2 plate has some play when 'locked down' (it won't come out, but it's not held firmly) – that means vibration and also adds to the challenge of precise positioning.
+1 on the advice to get an Arca Swiss compatible setup. The only Manfrotto ballhead I'd use is the 468MG, with a Wimberley C-12 or RRS lever release clamp on it. The cost of that setup isn't too far off an RRS BH-40, Kirk BH-3, or Markins Q10, all of which are excellent ballheads.
