Spinning Dilemma
Current policy is that a Fully developed spin and recovery is required for the initial FI(R) test. Incipient spinning is acceptable for the Revalidation. In any event you could opt to do the teaching work in one type and spin in another. Messy but at least you can be 'at home'.
Read the Manual/ POH and then find out how and when and IF you can spin your chosen aeroplane. If in doubt - don't do it until you have found out.
