[House Rules] Strengthening the Japanese OOB to make up for non-hidden play?

[Shad]

I'm trying to decide how much of a boost the Japanese in Guadalcanal & Jungle Fighting should get when not using the hidden Japanese unit rule in a scenario where it's provided. I do believe they deserve something...

I'm thinking 125~150% of initial OOB might make up for the loss of ambush ability... but I'm not deadset on it.

What do others who've played a bit of G/JF think? How much is that lost ambush assault bonus really worth...?
