The downside of a foam core wing is as I said, it's not for novices. There are assumed, or aquired skills, that not all have, not to mention some tooling such as vacuum pump and bagging equipment.
Sorry, this is where I will disagree. You do not need a vacuum pump and bagging equipment. True, that is one method to cover the wing, but plastic covering is very strong and is plenty to cover a finished foam core wing. A tried and tested method as I have witnessed myself.
