I have two classic traps and they are about 60/40 or slightly lower. They do shoot rather flat. Not the very best for trap, but I have used them for sporting clays, skeet, and 5 stand with appropriate chokes. I used one for quail hunting and it was a great gun for that. The stocks are a little short for me, since my arms are fairly long, so LOP isn't a real issue. One is in the process of getting a high rib barrel and a Jack West Stock, so I'll be able to remedy the situation for trap a little. The other one is a good doubles gun. I still prefer a flat shooter to one that shoots 100% high. My 3200 shoots very high and is not a good candidate for anything other than trap. My older 1100 traps seem to be flat shooters, except one with a step rib that shoots a bit higher. The field guns are right about 50/50, or at least mine are. The addition of a Monte Carlo stock brings them up a little for me.
There are a lot of great shooters that use the 1100s for trap, so if it says Trap on it, or it has the right barrel and stock, it's a Trap gun. They can be modified to suit your preferences easily enough.
