Maybe you should stick with what you've got for this year, but any new comers, or existing runners be made aware that running 13.5t is on the horizon. That way newcomers can decide to buy a 13.5t and any existing runners who need to replace dead motors do so with a 13.5t.
Having seen the boosted 13.5t's go round Mendip they will be more than enough for the Tivvy track.
It also opens more options to the Tivvy drivers to drive at other tracks with no extra cost or hassle in changing motors.
