[QUOTE=RShantz;20270924]I have an SLR & love it. However, if you couldn't tell the difference I wouldn't spend the extra $'s. I'd also suspect the SLR is less durable. Normally lighter weight does not equal more durable.

Is this correct? The lighter SLR (with Trek's 700 OCLV carbon) might not be a "strong" as the SL (with the 500 carbon)? I assumed that higher grade carbon would be more durable and long-lasting (under the same conditions) as the lower grade carbon.
