if done properly, lamination will significantly strengthen the wood while adding less than 1g. I personally would suggest using it with two light and flimsy pieces of wood. I usually like to laminate on the base. So basically, what i do is build the base and my partner builds the chimney and we both connect it.
so, i will build the base normally first but use moderately light pieces of wood for the four 1/8^2 primary compression members. Then i will take an extremely light and spongy stick of balsa (with a mass of roughly 1gram per 48 inches). Then i cut out a piece from it that is a tad bit shorter than my primary compression members, apply glue to one entire side and glue it to a primary compression member. Do this until each of the four members has a stick laminated to it... i find that this only adds about 0.4-0.6 grams to the base to make a 3g base. However, the strength benefits are worth it imo.
Laminating for the chimney is an abject disaster because the primary members are too long so instead, we just put more bracing
but if someone has an easy method for that, i would really be interested in knowing it.
a note on gluing: i find that super glue is pretty good for laminating but there can be some issues with weight and the fact that some varieties dry too quickly. You can also thin out wood glue with water. I dont know how much weight that adds but i would say that the lamination with that is pretty amazing(if you can get the right consistency of watery-glue)
another option is to just use something light such as welbond, ambroid, duco etc... oh but a warning: ambroid smells horrible, so avoid it if possible
