[Closed] Tell me about puncture proofing 700c tyres.

I worked out recently that it is over a year since I had a puncture on a ghetto tubeless mountain bike.

I've just bought a road bike and have searched the forum for advice and it seems tubeless is not recommended for higher pressure road tyres as it can affect the way the tyre seats against the rim and cause it to blow off.

I've never had much success with slime type tubes. Apart from the extra weight,they just didn't seal punctures for me.
Are some brands better than others ?

What about using latex in the tubes ?
I seem to remember hearing that Stan's or Joe's won't work in tubes. Something to do with the tyre and tube constantly moving in relation to each other meaning the object that caused the puncture won't allow the sealant to seal. Have I got that right ?
Is it still a problem on road tyres ? Isn't there less relative movement at higher pressures ?
Is it worth buying a pair of tubes with removable valve cores and giving it a go ?
