I'm going to suggest moving the FS back to their old starting squares right behind the geese (it's funny, but geese sounds wrong when one is simply referring to shogi pieces). My reason for this is because the silver cannon actually does a good job of getting in the way of the flying swallow. If you wish to bring the cannon forward, it takes several moves and likely exposing it to early attacks if you want to simultaneously bring the swallow out. And if you wish to bring the swallow out earlier, you have to retreat the silver cannon, making it take longer for it to be effective. As the two strongest pieces in the game, I think they do a good job in that position interfering with each other and preventing a player from making too much use of them too early. I might be wrong, but see what you think. I want to read your thoughts before my next move.
