Oh.... since no-one else is talking to you... ;-)
It seems to be the case that cushioning and support are mutually exclusive - one compromises the other. Do you really need a lot of cushioning? I'd imagine, if you've been advised by a physio, that you need support to stay un-injured, so maybe you need to go for that......?
Another thing - a shoe which supports high arches...? Sounds like a rarity to me. And over-pronation (excessive rolling in) isn't necessarily best corrected by an arch support - it depends on what happens through the whole range of motion. Probably the best idea would be to go to a proper running shop and get videoed or looked at to see what model of shoe makes you run as neutrally as possible.
All in all, I think the reason why you've had no answers is that there's no answer!
