I know it's personal preference but I find dual ply tyres lifeless and heavy compared to a Stiky Lite, awesome grip, light, bouncy and pretty good puncture resistance. Just can't see how you can say they're rubbish?! Wish they did a 24" version.
When I was on 24" trials I ran lightweight tubes (200grams) in a Schwalbe Fat Albert (690grams) and didnt suffer with punctures, now i'm reverting back to 24" it's the set up i'll be running again.
Personally I'd run a slightly heavier tube, slightly lower pressure and ride a bit smoother? Going light and being a heavy rider/bit of basher don't tend to go together too well.
