Not sure about the T67 but the Bulldog has a nice high-rot spin mode if the stick is moved forward during a spin whilst maintaining pro-spin rudder - a significant push force is required. Recovery involves returning to full pro-spin inputs and then using a standard spin recovery, if you reverse the rudder without the stick being on the backstop there is a delayed recovery.
Rate of rotation is significant and some people feel "spun-up" for a significant time afterwards.
Words to the wise: do not try this unless you are proficient/comfortable with spins, start at 10,000 ft, wear a parachute and pre-brief a height at which to start abandonment (4000ft?)
