We've got a ironman duallie which we got from http://www.bobgear.co.uk
they offer a 30 day money back return which allows you to try it out and get a refund if you don't like it. Here's the details http://mediacdn.shopatron.com/media/mfg/15587/spec_file/236183590.pdf
We kept ours. Hope that's of some use.
As above - using connect, set it up as run/rest and then set the repeat to as many times as you want.
I tried a pair and they sounded terrible. Maybe I don't have hifi bones.
I'm very happy with my Virrata's. Very light, very comfy and plenty of cushioning for me. I alternate mine with kinvaras. Sorry I can't compare them to green silence but fit wise I've got wide feet and there's plenty of room for me.
Saucony do a pair of shorts with a zip pocket on either side. I think they're called 'throttle' I got them from wiggle.
