GluLam, GluLam, Glulam.
Have I said it enough times yet? Despite what contractors love to tell clients, a sistered beam has only 1/4 the shear ability of Laminated lumber, or even better, actual lumber.
Take it from an architect, you will regret using a sistered beam. Besides, and 8' span is quite a small amount of work to laminate if your making the lam beam yourself.
But why don't you just buy an 8' peice of 10"x6" laminated strand lumber ? The price is low if you can't afford actual lumber with a large nominal size, and it has quite the compressive and shear ability.
