'Roller Coaster Ride' is very small, though I don't think it's listed as a mini. It IS, however, somewhat smaller than 'Curly Fries', which is listed as a mini (wrongly, I think). I grow them side by side. It's been in my garden since summer 2011; so it's fairly mature. It is a stable sport of the streaked 'Ray of Hope'. It has narrow pointed green leaves with a rippled thin white margin and it does well in full sun which I tested last summer after we lost a large tree. Please feel free to share your pictures of this hosta. The hosta behind it is 'Curly Fries' and in front is 'Allan P. McConnell'.
