Ok forget the above. I've just found the ideal set-up
HERE.
I read about the PicSkate blades a while ago but could never find anybody in this country selling them. And the alternative version from
OZ (
or these) is around £185 just for the blade.
So I've eMailed the company to enquire the cost of them supplying the blade fitted to the same model of boot that I use for ice skating.
This is a far better idea than playing around with wheel sizes to get regular short wheel based in-lines to act like ice skates.
