Which microbore? My thermobore has gone all hard now I'm back to cold water

had 6mm and wont be buying again,stick with the 8mm microbore dave.
6mm wears out to quick and springs a leak everywhere,brought two new lots 18months ago,1 real was replaced free of charge after 6months, and the new real is show signs of bad wear,and the other reel was replaced last week after 18mths,holes everywhere,and also kinks a lot more than the 8mm
the 8mm which I give away after 4years of daily use,is still being used today with no problems and must be over 5/6 years old now
