Joined rails as accurate and smooth as one long rail?

[Ross 71]

Here's my perspective.  Your ultimate answer will be what's right for you at the moment.  Handling long rails can be tricky, esp the 2700 & the 3000, and there are an increasing number of reports of the long rails becoming bent, curved, whatever.

Have there been instances of long rails becoming bent? I know a few guys have bought rails that were not quite straight when new(and were replaced) but this quote seems to imply that long rails become distorted over time

Anyone know about this?
