My comment is "Be careful what you wish for, because you just might get it".
My limited understanding and experience is that;
1. Flat spins may not be reliably recoverable.
2. An Aft CG position may flatten your spin, which is why you need to pay very careful attention to CG position (eg Alpha 160 - no more than 110 ltrs of fuel)
I must get out more and back into learning aeros.
