Was curious...  I have a BlackOut spinning rod from No.*** and was wondering if temperature had much of an effect on the strength of a rod.

Featuring advanced HTC3 blanks, which blend high modulus 30- and 24-ton graphite with No.8’s high performance resin

Do you guys have a rule of thumb for if it's too cold for a rod?

Also - how do you know if you're getting close to the breaking point of a rod?  Is there an audible feedback or something before it gets to that point so you know to let off?

In the spring there were a couple days ice was forming on my graphite rod and it did fine. Most materials will be more brittle at colder temperatures but I'm not sure the temperature range we fish in gets low enough to be of any concern. If you can cast a lure without it bouncing off the water I would think your rod should be fine. 

Ice fishing rods are made of graphite and you don't hear about problems using them on the ice. I'm sure your rods will be fine in any weather you fish.

As far as I'm aware naturally occurring temperatures will not have any negative affect on a graphite rod.

I assumed as much - I was mostly asking out of curiosity more than any actual concern. 

Thanks folks!
