How was your experience plugging the hole? I tried using dynaplugs on my GK slicks a few months ago, and even after reaming the puncture quite a bit, I had a hell of a time getting the plug to seat. When I did, it only held for a few rides.
It felt like the cut was too big for the sealant to hold, but too small for the plug to fit in. I moved on to the GK+ as well, but have had mixed luck with them lately riding with tubes.
