Not at all. There's no problem with either method.

Now question #2 what is the best glue for attaching balsa to foam, I was thinking of Great Planes yellow wood glue.
This is my first foam balsa build, I usualy go with built up wings.
Thanks
"best?" not going there. I would stay away from the wood glue. Do you have the foam wing cradles? If not, you will need to support the wing to avoid warps, no matter how you attach the balsa. I am familiar with two methods, epoxy and contact cement.
Epoxy - you smear it on the balsa, and squeegee as much off as you can. I used craft sticks. You want the wood to look wet, but not soakied. Then apply to foam core (in a saddle) and put the top saddle on, then weight it down with 40-50 pounds, walk away overnight. This is probably not a good method if you don't have the foam pieces the wing was cut from.
contact cement - Southern Sourgum brand comes to mind, but there are others. Apply to wood and foam, again very thinly, let dry, and press the two together. Done. The only warning is you only get one shot to put the two together, it is instant stick. Again, some sort of cradle will prevent warps.
Hope that helps.
