Planning a tri-lam longbow

[takefive]

In no hurry to get started, but I've been thinking about doing a R/D tri-lam.  Thinking of using hickory for the back, walnut for the core, and osage for the belly.  Or, should I pick a better wood for the core?  Would Titebond 3 be okay for the glue up since it's all wood to wood or should I go with Unibond?  Thanks.
I finished my BBO and will post some pictures soon.  Thanks to you all for the advice on that one.

I'd opt for unibond because of  the gap filling capabilities .

Thanks again Mac.  Unibond it is.

Definately use the Unibond for several reasons, longer working time, better gap filling are among the best.  Black cherry makes a really good belly wood with the hickory and walnut.  In fact, its my favorite combination to date.

Glad that I listen to you guys.  I don't have a more precise way of getting the lams flat, just used a belt sander.  Unibond did a good job of filling in the small gaps I ended up with.  Just started tillering and so far so good.  Menards sells cherry boards.  Will those work?  Or would I be better off trying to find black cherry at a lumber yard?
