I understand that spins aren't allowed now in PPL
Not strictly true. They were removed from the ab initio syllabus several decades ago because it was killing too many instructors. Intentional spins are prohibited in many training aircraft types, but not all, so if you ask during your course, your instructor might well demonstrate one to you. There's nothing to stop anyone post-PPL doing spin training in a suitable aircraft with a suitably qualified instructor. I'd recommend an aerobatic trainer such as a Decathlon or Citabria because they can be properly developed in the spin. All UK SEP instructor courses demand the trainee instructor demonstrate a recovery from a spin during the test.
What IS in the syllabus and MUCH more relevant to PPL flying is recovery from the incipient stage. Most spin accidents happen very close to the ground where traditional recovery techniques are useless. It's much better to learn to recognise the symptoms of an approaching stall/spin and recover from that.
The nay-sayers back in 1982 who said taking the spin out of the PPL syllabus would result in wholesale carnage amongst pilots have been proved completely wrong. People continue to die from spin-related accidents, but invariably at heights from which recovery would have been impossible anyway.
