When I first started riding trials in the stone age, I would set the idle stop on my Greeves for no-idle - the slide allowed to bottom out with minimum cable slack. I did it that way all through the years, 2s 4s and including TLR Reflexes. One reason was it acted as a crash kill mechanism. It also taught the right hand to 'feel' for the slowest tick-over when desired and allow no-gas retardation on the downslopes.
Now I have a modern model, the TRRS 250, and it is set up by my dealer with an idle. I rode it that way in the past club event and it seemed to work fine. Is that how everyone is doing it now? I was thinking of practicing with it both ways but it would be good to hear informed opinions. I am posing this question on my club's Facebook page too.
