Thoughts on my 40k army

So...I am kind of at an impasse with my 40k Blood Angels army. I currently have it set up for 2050 points for the third Mind Games tournament coming up in August. The list I have worked out is roughly:

Dante, Lord of Blood Angels
Death Company w/ jump packs x4

Venerable Death Company Dreadnoughts x3

Ten-man tactical squad mounted in a rhino x2
Five-man tactical squad mounted in a razorback
Five-man assault squad mounted in a rhino, accompanied by Brother Corbulo

Predator tank with autocannon and heavy bolters
Baal Predators x2

I have played a couple of games with this army, where it performed much better than my previous army lists. Still, the thoughts that other players have had is that Dante is just too expensive in points (200) for what he does (which is a lot). Also, once Dante is down and no longer giving his fantastic bonuses to everyone around him, the army kind of starts to fall apart. Also, Corbulo is the one preventing the death company guys and death company dreadnoughts from running all over the place with compulsory "rage" moves. Having him mounted in a tank (I can't give him a jump pack) tends to make the army unwieldy, and eventually some of the death company stuff gets outside his control range and has to make their compulsory moves. There have been suggestions that I take a regular Chaplain or the special character Lemartes (who comes with a jump pack) to control my death company stuff and drop Corbulo. Still, I think that having Corbulo mounted in the command tank makes him very survivable, whereas a jump-packing Chaplain tends to just get gunned down (which is what happened in my games in the previous two tournaments).

So I don't really know what to do...keep my list the way it is and refine my tactics to better shield Dante, and make better use of his and Corbulo's special bonuses? Or take those two characters out and use the points on something else? The only thing I can think to do would be to drop Dante and use those 200 points on some Witch Hunter allies; most likely just some extra troops choices. But then...no super-over-the-top Dante bonuses. Also, I have almost completely painted everything for the list in its current state. I would have to buy and model up those witch hunters...which is a giant pain.

So I am thinking...I will keep the list as-is, and try to get in a few more games where I will work to keep Dante better protected until he makes contact with the enemy, and also keep the army together. I generally split the army, with a main thrust containing all of my goodies, and one predator, the razorback, and maybe another unit or two sitting back to shoot. I think that I would fair better if everything was just together, in a single big armored column that advanced on the enemy. I would be very vulnerable at that point to big template weapons, but since everyone BUT Dante and the death company are mounted in tanks, generally a big template weapon is still only going to destroy a single tank.

Decisions, decisions....
