Excellent question! Now that we are working more than ever with using rods in fusing projects, we have gotten well-acquainted with what to expect from Bullseye rods in fusing.
Information is available in our FAQs, which is fairly well buried in our website. I have links for your reference:

For learning about whether or not each rods style is suitable for kilnforming, check TorchTips (which should really be called, RodTips!). http://www.bullseyeglass.com/education/torchtips/
If you want to explore this topic with an expert, consider taking Bonnie Celeste's class at the Bullseye Resource Center Portland: http://www.bullseyeglass.com/education/ ... ng_rod.php
