As spinning was not included in my JAA-PPL training, I became curious and did some spins in a Citabria with an aerobatic instructor. Since this experience, I am with BPF et al. and the powers-that-be who removed spins from the PPL syllabus concerning the potential safety gain. Intentional spinning at altitude is one (even quite fun) thing, but if one really messes up so badly as to get in an inadvertent spin at low altitude in the first place, I doubt that anyhe/she will have enough time, height and mental resources left to make a successful recovery.
IMHO, from a safety standpoint, an ounce of prevention, stall awareness and emphasis on an immediate "Stop pulling the stick/yoke back!" at the very first sign of trouble is worth more than a pound of actual spin recovery skills.
