Nice little write up on spins here:
http://en.wikipedia.org/wiki/Spin_(flight)
An advantage of foam is the low cost and quick repair. If we do build a club plane it would be a good idea to have spare parts for several rebuilds or new planes, these could all be made at the same time. With a foamy you can use templates which can greatly speed up construction. I would think EPP would be ideal as you can sometime bounce planes built with EPP.
On the other hand balsa has its advantages. Getting a design that is quick to build and repair is the key. Maybe sheet construction without a lot of small fiddly bits and balsa is stiffer than foam.
