Share 'The FLX ESP plastic...'

I have just purchased a FLX ESP surge SS. This is the first for me as far as the FLX goes. How is this plastic?. It seems really flexible but how about when in the heat? Does the heat ,say 90 and above, make this plastic unthrowable? I do like the grippability(if thats a word)of the plastic though. I hope to give it a test run tonight or definitely tomarrow.
