the clark ones. they feel nicer, the halfords own ones (grey and yellow packed ones) are crap, way too thick and way too soft, last about 2 weeks if that. Trials tech, last forever, had mine on my bike for well over a year, changed them had them on and off bars. no reason to buy anyothers,
Pop em on with a wee bit of hair spray...... stickes em tight. (bit we all know that)
