I just used TBII, since it was long grain to long grain, figured it would be ok. It grabs quick, I just hold it for about 30 secs and leave it alone. On larger boxes I have made, with thicker walls, I use my biscuit jointer to cut in an incision, then fabricate the handle from there to give me more glue surface. But that is a little of a pain. This is quick and easy, and allow me to use a thinner profile, which I like.
