Yeah, I think you're right ... just one of those things, but always painful when it happens in the Main!
You'd think with all the titanium stuff out there that someone would make pins too ... but perhaps it's better that they do shear off rather than transferring the stress to other more expensive (& harder to get to) parts. I might experiment with cutting some piano wire from the LHS down to size ... then again I'm pretty lazy too, I'll likely just make sure I have a good stock of pins on hand and replace routinely before any big races.
Speaking of 'big races', I'm going to one in a couple of weeks, the Missouri State Champs in Chillicothe, Jan 24-26. It's a very nice facility, but VERY different from what I drive on at our club track.
We should have a ton of Region 8 racers there, even though it's not an official ROAR event (that's usually in August). Wish me luck, I'll need it!
