This thread discusses the Content article: Bryce Speed FX (Butterfly)

How is the durability of this rubber?

I ought to go and edit the post and put a figure there, but maybe I'll give it a few more months.

I just went back to another forum to find out when exactly I started using my Bryce Speed FX - and I can't believe it's been almost 4 months already! My rubbers never tend to last this long. It still plays extremely well - I'm still getting good topsheet spin - and overall I'm very impressed with this compared to any of the tensors I've used in previous years. I like this more than Optimum MP and Couga, which to me felt rather dead after a couple of months (and I rate Optimum MP higher than the Almanas).

One thing is different from my original review here - I transferred my Bryce Speed and Speed FX over to my Iolite, and I must say that it's an awesome combination. One or two people who have tried my racquet thought so, too. I switched over to using Bryce Speed FX on my FH instead of the BH (initially), because my FH is a bit less controlled than my BH and the FX definitely helps here. My coach thinks it's OK on the FH, too (and he normally likes a harder rubber on the FH than the BH).

Bryce Speed FX does not have to be reglued correct?

That's correct. According to the Bty website it has a high "reglue effect," meaning it responds well to speed glue.

So, you can use it either way. I don't use speed glue these days.
