I looked into it too. Unfortunately I have committed to doing Stay Upright rider training day on the same date and they only come to Tassie once a year (if not at all).
I went to the Distinguished Gentleman's Ride website to see the details of the local ride but found it incredibly frustrating that you have to register for the event with all your details including your bike, date of birth, email, phone number, full address and even your motorcycling philosophy.....just to find out.
Anyway I hope you enjoy the day and it is for a good cause.
I agree with Scot, plus I don't have another bike to choose from - so for me it's the GRiSO or it's nothing.
