Thanks Duncan!
As we did last year we ran Kumho's medium tyre (not only because they helped us out a little, but because we LOVE them - they're are massively underated). These tyres perform well in the dry, but are absolutely AWESOME on wet conditions. As we were aware on arrival that it would likely be mostly a dry event this year, we were taking it very easy on these in the first few days, and experimenting with pressures etc to try and minimise the wear. Suprisingly, we found the GTR looked after them at much higher pressures this year (around 38psi vs 25psi last year in the Sti - cold).
Half the battle as you know with Targa is getting through on one set of rubber, no use headin out like a hero only to be told you need to change a tyre and cop the penalty (ala Beatty etc...).
Overall, they were really good, we only overheated them on one stage (Sidling), but they came back well. The last few stages on day 5 saw it wet, and we actually passed a front running GT3 within about 100 seconds from the start line (leave at 30 sec intervals), so yeah, in the wet, I don't know a better tyre. And we really have tried them all!
We still had a little tread left at the end, so I think we timed our push pretty well!
