I play different units just my style and what works for me but not that big of a diff. i will unload at times but won't let 1 play put me in the red if i go 4-1 I see where gm is comming from, hope you win it, and GM was just trying to help out some, it is ok to have different units on games but a big over lay can give you a big set back hell i never had a 25 unit play but depends on your unit value which is personal and no-ones business but yours, but that is a big over lay just trying to help, it might work a few times but it will bite back and when it does it hurts, it's almost like playing catch up, maybe try and stay with in 3 units on bigger plays, but hey it's your money just seems to tilted on 1 play for me. good luck not a bash just trying to let you know it is a big over lay more then i have seen and i do this out here every day.
hit it i hope if not nothing you can do but you need to be able to live to play another day.
good luck
Eric
