If you get a good finish on them - ie, get them sealed well - they should not warp and hence should last a long time. OTOH, they will be susceptible to permanent deformation if they, for example, get left in a distorted position for a long time, such as when the rocket is laying on its side resting on the fins. That is, balsa won't bend but fiber will

Anyway, I'm glad you're building this. I keep resisting the temptation to start a clone, knowing I already have enough projects going, most of them in extended duration limbo
