So with the fist of medussa you can run a armored core as your core right? So can i actually run a whole list with no guys except 1 techmarine? Maybe a contemptor or two?

Some thing like

3 pred annihilator so the have tank and monster hunter, and with potms they can split fire
3 dakka preds in different units
3 vindicators
1 contemptor

Would this work and has any one been doing this, I am sure its fairly comon i guess but if any one has so ideas as to its main weekness i would appericate it. As this is just a start there is many ways you could go

Would whirlwinds be worth it?
With staying in the formation how would you get another techmarine in there with out running thunderfire cannons as they are expensive to buy?

All vehicle list armies tend to either go big or go home. At least Guard Tank lists do, and they're AV14/13/10 hulls. Either your opponent brought enough Anti-Tank that you just get blown off the table, or he didn't in which case you blow them off the table.

Deep Striking units (Crisis Suits, Drop Pods etc), fast assault units (bikes, Thunderwolves, Flesh Hounds, Wraiths, Jump Monstrous Creatures etc) and even just mass S6/7 shooting (Scatter Bikes, HYMP Broadsides etc) into your side armour will do a real number on you which you have no real counter against.

Thats a great point. If i work in some dreads do you think it might be worth it or maybe one sort of counter assult unit?

I thiiiiink you need IC's to get POTMS in the fist of medusa list.
