I'm going against the trend, but I think the synthetic is reed 1, it sounds very consistent and even up the scale, where as reed 2 has that occasional cane quirk that throws a curved ball towards the top of the scale making it slightly less even.
But to be honest the differences are so slight that I'd reckon you would have equally minutely different soundclips if you used the same reed and had just taken the reed and ligature off and put them back on again.
Pete the tone is one very important thing, but how does it feel against the lip and when using articulation?
Best wishes,
Chris
