incline bench press

[Coolridge]

I have always heard and used 30 degrees max to keep my chest in it and my shoulders out.

yes me too, and i noticed that gustavo badell uses the same incline for chest, at least stated in march's Muscular Development mag (if you can believe the write up as actually being his) but i was curious as to what the remainder of the populous does?
the 30 degree angle was also sited for exactly the same reason....... but so far no proof, yet i know what i feel......
thanks
