1500pt Expansion (Baron List)

I'm looking to expand my 1500pt Baron list to 1850, the local tournament standard. Here's my current list.

HQ:

Dedicated Transports:

Fast Attack:
4 Beastmasters, 5 Kyhmerae, 6 Razorwing Flocks

6 Reavers, 2 Heat Lances, one is an Arena Champion

Heavy Support:
Voidraven Bomber
Ravager: 3 Dark Lances
Ravager: 3 Dark Lances

I would like to expand this list to 1850pts with 2 Kabalite Raiders for objective capping. I had initially planned to keep 10 warriors in a Raider with Splinter Racks and Night Shields, but after reading Nafka's Blog, I'm not as sure. He suggests keeping the warriors out of the raiders, and giving them a Sybarite and Splinter Cannon to camp in the backfield. The Raiders can then block line of sight and enemy movement. This makes sense to me, and fits the role I had intended to use them for better. I thought it best to ask here first, however, before making any decisions. Comments & Critiques are, as always, greatly appreciated.

Maybe eldar allies? Farseer + 2x3 Jetbikes can enhance what you already have in the list, which is solid on it's own.
