I don't know why the trend on so many newer made doubles is toward less drop at comb...... and at heel, on most. Many of the Italian O/U guns are stocked like that now. I have friends who shoot Guerini(s) and they have often offered them to me to try. I have never seen one yet that wasn't stocked too high for me. Obviously there are folks whose distance from their cheekbone to their eye is much less than mine.
I have a Verona 28/410 O/U two barrel set that is stocked way too high. I only use it for sub-gauge competition, and aesthetics is secondary to proper gun fit, so I put an adhesive backed add-on rib, 1/4" high, on top of the vent rib on both barrel sets ($40 ea). Instant gun fit. It lifted my line of sight that 1/4" that I couldn't get comfortably by burying my cheek into the comb. I would recommend trying one on any gun that one is considering having bent for more drop, before doing so. If you don't like the looks of it you can remove it with no damage to the vent rib, and at least you'll know how much you need to have the stock bent down. You may well find you shoot better with it because your head is usually in a more upright position, much the way the old-timers shot in America with stocks that had/have 3" DAH.
Brister, I believe, wrote about making a balsa try-rib to add height to a gun's rib, to test for proper fit and resulting pattern placement. It is said he was one who would take a rasp to a gun in a heartbeat, if needed, to try and make it fit him better. Shaving away the comb height accomplishes the same thing as elevating the rib, but is much harder to put back than removing a glued on add-a-rib.
