1st- what type of adhesive do you use? I’m assuming smooth-on but assuming is dangerous.
Unibond800 glue.
2nd- what is the benefit of a trilam such as this over a straight up BBO?
Trilams, being 3 pieces rather than 2 pieces, the belly and core lams are thinner.
Therefore it's easier to bend two thinner lams than one thicker lam, so they will take on a smoother sexier bend and hold it better..
For a BBO, I made the belly lam 1/2" thick. Pretty hard to bend a 1/2" thick board to any degree!
For a trilam, the belly is 1/4" thick and core lam is usually 3/16th thick or even less depending on poundage I need.
