Hi Graeme,
Thanks for your advice, much appreciated.
I've actually found my favourite Rotosounds went on a treat. There was slightly too much wrapping around the B String, but no rattles, and the tuning is stable. Too early to say for certain, but it's looks like I'll stay with this set up.
Might be visiting a mate in Perth sometime soon, I'll keep an eye on your website, and if it's good, I'll pop along to a gig, and sink a couple of heavies, I'm usually always thirsty.
