Eagle,
Either you're doing it correctly, or you're not. There isn't a half way point in a spin. Either the aircraft is spinning, or it's in a spiral. If damage is occuring or stress occurs to the airframe as the result of a spin, it wasn't a spin, it was a spiral. The two look the same, but there isn't an airspeed increase in the spin; it's in a stalled condition rotating about the vertical and longitudinal axes (and frequently the lateral axis, as well).
One cannot afford to say that simply because one has less hours or experience, pushing an airplane to it's limits is acceptable, or will simply happen. Not good enough. If a 400 hour instructor is incapable of doing it properly, then he has no business doing it or teaching it, period. That's what the instructor is paid for; not to learn at the student's expense (and potential risk to life and property).
With respect to spinning, as no undue stresses are placed on the airframe, the strut strength makes little difference. To spin or not to spin comes down to two things: certification issues (is it legal), and capability issues (is it safe). Unless both can be answered in the affirmative, then it simply doesn't fly.
