We used a red marker to paint the tips of some old AA guns to denote rockets. We did it mainly to remember you have rockets. It really sucks when you forget to fire them, it happens every now and again. You could also paint them another color to denote radar.
Keep in mind however, subs alone always reserve the right to submerge before even the Attacker rolls his dice. so essentially, without a destroyer, you can NEVER attack subs unless your opponent allows you.
I still view the Allies with a slight adv b/c of the number of Round 1 attacks the Axis must do, particularly Egy.
As for bids, we didn’t use them in our tourney and the Allies are holding their own quite well. I think they are up a few games thru 23 games. It might be like 13-10 Allies right now.
In the League we do use bids, but that is also used to determine sides. A lot of times both players may bid 0 and just let sides be chosen at random.
I did just post a few stats in the League Forum (thru the first 12 completed) in the discussion thread and the Allies hold a 7 - 5 Adv in wins. Avg bid was 1.3, but 7 games were played with a 0 bid and 2 were played with a 1 bid.
