I'm pleased to hear it's a relatively simple job, but that can depend on the hand holding the screwdriver.
From my perspective, it's the ST13's only disappointment, so I'm likely to join the queue to do the job. It's comforting to know Call-Me-Steve is just up the road if I get in deep doo-doo.
I got the blue GiPro having had the red a couple of times. It's a tiny bit distracting at night when I've been known to get startled thinking I've been on high beam. I might try the green version next time. As for the panel, I think I'd forego fancy and just go with the white. It works for the Beemers.
