How to do OBA in Infantry Attacks

[treadasaurusrex]

Infantry Attacks 2nd Ed created the 3 hex bombardment pattern. I can 2 ways to deal with this. There is the 3 counters option, which would be be put down in the designated hexes. That is easiest for me and no orientation problems.

The more complicated way would be create a 5-hex counter, 2 of the hexes would have transparent non counters in them. The counter would also be reversible and orient with the hex grain. More complicated for me maybe not that useful for players.

Are there opinions or other ideas?

My vote is for option 1 = the 3 counter option.
