So, I REALLY like the 910. A lot... But, always worried on carbon vs alloy and the 930 seems to be the same as the 910 with exception to the carbon main frame. Anyone here choose a 930 over a 910? Or even, did anyone look at both and pick the 910 due to whatever?

Looking for input as the pricing is about $1,000 and want to see that if I buy a 930, can I shed some weight and make it better?

Looking for some relating reviews before I commit...
