Like BrewBama I find the key is a gentler boil.
I go 60 minutes too, very very gentle. Just a bare simmer, enough to give good circulation, lid on except for a mere crack, until the last 15 minutes. Then the lid comes off and the heat goes up some to keep it circulating well.
But the index of thermal loading is really evaporation I think. The difference I've seen in wort quality between under 60, gentle, and about 6% evaporation, and any process giving 10% or more evaporation, is night and day. And the impact on beer quality and stability tracks also. Advantages in flavor and aroma, foam, all sorts of things.
So boil length isn't the real thing, it's total thermal loading. Think the area under the time/temperature curve on a graph. You do need some time to utilize hops, and you need good circulation to coagulate protein.
