RH tyres are expensive (not far off a decent car tyre) but I've not bought anything else for a while. At 26" I'm using RTPs (Compass versions) and Humpties, with 26 mm and 32 mm in 700c. I've not worn any out yet. I've had one puncture in a rear Cayuse Pass after hitting a tarmac pothole that also bent the rim. Lightly used versions appear occasionally on Ebay for about half price.
