I sincerely hope you are wrong, pikey! The two kinds of racing are totally different, the mountain course an individual test of skill, needing memory, control, calculated risk-taking - the sheer thrill of being able to ride a familiar and varying road the way one should be able to ride any road, were it not for the presence of others!
Not many things in life have really frightened me, but mass start racing alongside many others, some of whom seem to undergo a frontal lobotomy as the flag drops, on a circuit with stone walls, bumps, lamp posts etc....let me just say that IMHO the Billown circuit and Oliver's Mount should be in the same category as the original Nurburgring - ex-circuits. With the extra prestige that the TT title would bring to Castletown, too many riders would become too brave, with the inevitable result. Keep the TT on the mountain circuit.
