Wow, that looks nice, but pricey. I must try that sometime when I feel flush.
I just use whatever my lbs have around. I've seen two kinds so far by several brands. A solid coloured one and a translucent one that seems a bit nicer and more supple. Both plastic. Both colour coded for size.
Thanks dron. what would you recommend? something like this
