I would be surprised looking at the shape if the Cri-Cri is unspinnable, but I have been wrong before.
Re: the Shadow, I've flown most variants. I enjoy them, but will dissapoint you by saying that in my opinion the very best of them is the Rotax 503 engined Shadow CD. My biggest gripe would be the sheer number of materials and relative fragility which means it absolutely needs to be hangared.
But if you have a hangar and don't mind putting work into any maintenance tasks, which possibly includes developing some new skills - they're great little ships. Don't be afraid of 2 stroke engines, particularly the 503 which is a superb piece of engineering that just needs you to stay on top of the scheduled maintenance (but you should on any other engine too.)
