Thanks for the reply everyone.
I'm now under the assumption that 10speed cranksets are different than 9speed crankset, whether it be the chainring thickness or the spacing between the rings.
I'm kinda bummed out because with the FSA Vero triple, I just kept it in the middle ring and I could reach the every cog in the rear.
It looks like even Shimano admits the middle ring + small cog combination may rub.

I though about going the spacer route, but I might try the 10speed chain first when the current chain wears out.
