The syllabus requires 2 hours minimum of stall and spin awareness, expect to do a bit more than that when you include slow flight. The -161 is not cleared for deliberate spinning (nor are most PA28 variants), but in any case spinning hasn't been a part of the PPL syllabus for over 20 years. The reason it was removed, was the belief that more accidents were being caused than prevented by the training, and historical data bears that out, despite the fact that many "old guard" have been arguing for the re-inclusion of spin training ever since. If you want to learn about spinning, there's much to be said for it, but it's outside the syllabus - see if there's an aerobatic instructor and suitable aeroplane in your school, but don't do it until you've done at-least 10 hours flying (preferably 20), it'll just confuse you. The bulk of your training will be about avoiding the stall, rather than actually stalling or spinning. The flying characteristics of any PA28 make them extremely spin resistant anyhow, and you'd have to try incredibly hard to make it. The same to a large extrent is true of the stall, which requires a great deal of pull and to the best of my knowledge nobody has ever killed themselves through an inadvertent stall in a tapered wing PA28 (which includes the -161) in the UK.
Any questions?
