Ah, at last, thanks for the info Carolyn! Doesn't sound like I need to bother buying a wetsuit then, good stuff!

I try to keep weight to a minimum in my rucksack as I'm getting a bit old and frail these days.
I will endeavor to do a Just Back Report concerning jellyfish and anything else of general interest when I get back but that might not be for a while I'm afraid. The Gilis will be a luxury rest stop before I head off for Komodo Rinca Flores etc on a leaky ferry. Then, depending on how far I can get on a 2 month tourist visa, was thinking of going back to the Togeans again and if I have time possibly check out the Banda Islands too, using leaky ferries, local buses and the crash prone budget Indonesian airlines. If anyone else is going too, give me a shout. It would be nice to have some company this time. Last year during Ramadan there were hardly any other Western tourists about on Sulawesi.
