The deeper the board, the less you compress your bellows. This gives you more wiggle room.

The deeper the board the harder it is to get your fingers in it.

Cameras vary. On the 4x5 Tachihara I had you could use a 90mm on a flat board. If a 27mm recessed board will work for you then I would go with that.

I believe that Horseman cameras are compatible with Sinar bellows, no? If so, a Sinar w/a bellows will eliminate the need for a fiddly recessed lens board. Although a 27mm recess should be workable even with the standard bellows.
