Innegra & S cloth - Hand lamming?

Is it worth using innegra or s cloth if hand laminating, or do you only get the full benefits from vac bagging?

 

i have some cloth that is 1/2 innegra and 1/2 fiberglass woven together and it was pretty easy to laminate by hand. 100% innegra is going to be hard to deal with if no bag
