Yeah definitely I agree with all that has been said... incline and decline flyes are great movements for hitting your pecs from different angles. Decline flyes I dont like too much but theyre good none-the-less if you have problems with your lower/outer or lower/inner pec developement. Your can really focus on squeezing your pecs together and focus on the stretch as well. I personally have problems with my upper/inner pec devlopment so I like incline flyes squeezing the dumbbells together at the top. Variety is great when it comes to optimal pec development in my opinion. However you cant avoid the basics... dips, incline barbell presses, flat dumbbell presses, etc.
