Tim,

the Tornado dont have the hull volume to support more weight. In addition many old T's are underbuilt for the new rig (and might not be built to last for the pinhead rig as well). Any old Tornado besides Marstrøms fresher than 86 is a 'maybe'. There are some nice Gougeon and other wood boats, and probably some Sailcraft and Reg Whites worth investing time in but you need to know the boats to find the gems.
