The flesh tearers one.
I like your list, it looks like a lot of fun. I do feel that you are light on objective secured units, making it hard to do well in objectives games. Plus
MSU is vulnerable in kill points games, so you're struggling on both ends there. An alternative would be to go for chimeras or tauroxes instead of razorbacks. The change is guns is significant, but I feel like the chimera's
AV 12 obsec is a pretty sweet deal as is the points savings on both it and the taurox. You could go either with forward sentry vets or with a blob who takes transports anyway. It's not cheap points wise, but I feel that it solves two problems pretty elegantly.
I'd consider a bunker for the destroyers.
If you're running Elysians anyway, I'd love to hear a report some time on skitarii jumping out of Valkyries.
