thumb throttle control keeps breaking

[andyv]

I got a kit maybe 4 years back which included a thumb control and a twist control. So far I've broken two thumb controls - mainly due I think to banging up to things on public bike racks. I've fitted the twist control but don't like it and want another thumb control but I need something more robust. It's the plastic projection which breaks. Does anybody do something more durable?

OK until I find something better I've attached a lump of Sugru which seems to do the job.
