Firstly, I like this list. I'll stick to the second one, as it incorporates a bit of the previous feedback.
reclusiarch with infernus pistol 145
I did this for the first year of 6th against mechanized IG and cut the IP off my Reclusiarch. It's cool, but yeah. Ultimately just not worth it.
10 death co, powerfist 225
LRR with MM 250
Something I've started doing at 2k is play a smaller sized DC in a normal LR as defense with my ADL and Scouts that man it. Alternately I was always putting my DC in a Stormraven (one of my two that I played at 2K before for air defense) but since the addition of the ADL I have wanted to try more things. GW made a LOT of money giving ADL's Interceptor and Skyfire. The idea is that the LR sits back putting lascannons into armour and forcing meltas to advance, but I've got a 6" move, 6" deployment and (most often on 2 d6) a 7" charge range. Unless there are multiple Melta units advancing, that's a greasy counter attack. The twin linked lascannons are also nice as a last resort against fliers. Just a thought keeping a LR in there. We shouldn't be so scared to field them in 6th, it just takes a new strategy.
10x assault marines, 2x meltagun, powerfist 235
10x assault marines, 2x flamer, powersword 215
furioso, frag cannon, h flamer, drop pod 170
sang priest with jp 75
baal predator with assault cannon and heavy bolters 145
F&*K yeah. I'd be wary of having only two squads of scoring units, but you will feel that out in your first couple games and see what you need to do. I'd keep them together to use the Priest to his full effect and only break one squad off for a second objective towards the end of the game if it mattered. Dice make all the difference to all things.
I've always wanted to do this. I've heard great things, though personally I'd take a 5 man sniper scout squad w/camo cloaks and an ADL and use the remaining 90 points to do anything. Alternately to the Scouts, a ten man tactical squad and the ADL w/quad gun still come out to less than two Vindicators and have just as much tactical use as two pie plates and WAY more survivability. Just not as much BOOM. Scouts I feel are better in the ADL as they will have a 3+ cover save with their camo cloaks. Nice. Three games for three just yesterday I had those scouts kill many things. It got to the point where my opponent had given up on shooting them as he just couldn't beat my saving throws.
Hope this stuff helps!
