I'm thinking of adding some Bullgryns to my Guard army as they're great models and I have some ideas for some minor conversion work.

Only problem is I'm unsure how best to use them so far I've have 3 ideas...

3 Bullgryns and a Priest – The unit will be fielded with my Hellhammer super heavy and escort it around providing it with a 3+ cover save and most of all prevent charges by units such as knights, terminators, etc. They might not last long but that will afford me 1 or 2 more turns of shooting with the lord of war.

3 Bullgryns, Priest & Yarrick in Chimera – Someone suggested this unit as a in your face unit that will cause some serious damage if not dealt with after they disembark from their transport, only thing that troubles me about this unit is it's expensive cost and the fact it has to endure a turn of shooting.

4-5 Bullgryns, priest and Yarrick on foot. - A nice bulky unit to draw fire or slow down enemy units going for my lines, I plan to have a nearby psyker providing biomancy support as I think it's too dangerous to have him in the squad due the fact Yarrick will execute him if perils happens. Could give the bone'ead a power maul and shield for extra damage and protection.

I'd be grateful for any suggestions or advice on how to get the most out of a Bullgryn unit, also if anyone has any experiences they can share playing with or against them that be very helpful?
