Thanks. Finally worked out what my ratios are equivalent to on my road bike (probably should have done that at the start, but hey)...
44x17T (70.0 GI) - equivalent to 50x19T or 34x13T
39x21T (50.2 GI) - equivalent to 50x27T or 34x18T
Enjoying riding this. 32mm tyres just roll over all the cracks, I'm glad I went for them over 28s.
