Frame Sizes

[Tonberry]

I'm after a 2011 Rockhopper, but I'm not sure on frame sizes.

I'm 5'9 and I'm looking at a 19 inch frame but after looking around it seems I should go for the smaller size of 17.5 inches.

My inseam is 32 inches.

Nowhere seems to have one in stock at the moment so I can't really trial one either.

Thoughts?

Oh and by the way, if it makes any difference, I'm just under 15 stone.
