Turkish Juicer mentioned cable cross overs with strict form which are an excellent shaping exercise; and some else mentioned doing these "gorilla barrels" as I call them from the lowest position....I concur this is a good variation, but thin that putting the handles at various heights including a high position will also help greatly with shaping. Remember to go slow, concentrate on form and negative rep with cables and squeeze.
A side note: your chest can't grow without compensatory growth in the back: meaning you need your lats involved in certain parts of the motion with very heavy weights while benching to help stabilize the movement, which allows you to lift a heavier weight. Have you considered strengthening you back to increase your performance on bench press?
As for decline presses they do take out some shoulder involvment, granted. But, remember there are only 2 parts of the chest, upper and lower; if the incline presses stimulate the upper chest, then logically, flat bench stimulates the lower. Also, it's nice to have athick upper chest to balance the lower, otherwise you end up looking a bit like you have boobs in profile.
Food for thought.
