Would be good to hear how you find them once you've had them fitted a while.

You must have run your Sirac's really bare then from what you said. I still had nearly 3mm tread on my rear when it was changed at 11.5k miles and never any serious slips.

BT45's still doing well and showing early signs of some squaring at 5k miles so far, looks like they should be good for 10-15k miles or so again.

Cush drive shows signs of being shot after the same distance as the tyres though. At least as the chain is ok this time I can tell what it feels like (guess I'll get them replaced at the 18k mile service)
