Hoser,
Maybe if you describe the gun; weight, gauge, etc. and your intended use, it could help others understand a bit more. 
For example: a 6 1/2 lb straight stocked, splinter forend, 12g is likely not gonna end up your favorite clays gun. But it may end up your favorite upland gun.  If you don't hunt over a dog or have a flushing dog that hunts out a ways, you may want it tighter choked than if you had a rock steady pointer.  
There is plenty of use for full, IMO.  But not 4 barrels full of full. 
I still think if you really don't know what you want, make them in the classic set F/M and M/IC.  You can open them more if you feel the need.  Harder, by a lot, to tighten them.
