Am using GP4 Seasons as am so pleased with their bullet-proof performance.

At the moment have standard Conti RAce tubes, but given the tyres' superior puncture resistance, would value views on going for either Race Lite or Supersonic butyl tubes?

Yes, could go latex, but think for me the downsides outweigh the advantages. So, Race Lite or Supersonic? pros and Cons?

Thanks

Supersonics are relatively expensive compared to the Race Lites and considering that the tires aren't exactly light at around 240 grams it seems like a waste.
