Wow, I didn't realise this thread was still going!!
As you may see from the For Sale section, I'm unfortunately thinking of selling my Triple O. It will be heartbreaking for me if I decide to go through with it, but I just can't justify having such a bass and not being able to play it, and to try and keep it purely for its aesthetics (i.e. there are other smaller, lighter basses - including some Alembics - out there which could do pretty near as good a job) just seems some kind of vanity. And much as I appreciate the suggestions, I think carrying a stand around in order to support a bass I can't otherwise play... well, I can't justify it.
I'd like to thank everyone who has contributed to this thread and who has offered advice and support, with a special thanks reserved for Rich who has e-mailed me off-forum a few times and who I have been somewhat remiss in getting back to on time (Rich-I hope you're well!!!!).
Thanks very much guys, you're the best.
