Space Marine 1,850 - Count-As Iron Warriors

This was something I was thinking could be fun. It's something that I think is fairly competitive even against extreme builds. It also moderately fits the theme for the models I'm building.

It's 1,850 on the nose. For the theme I'd prefer Heavy Flamers or Las/Plas on the Razors but currently don't have the points to spare. It's got two Multi-Melta bunkers that score with 4 more scoring units in the form of the combat squaded tactical marines. I figure I can model out the Honor Guard as pimped chosen and they are death on wheels for anything without a 3++. Vindicator for hopefully picking off those pesky termies and TWC. The army has a solid CC element especially with the added attacks that Pedro can add. Overall I think it can hang. Thoughts fellas?
