I am thinking about trying the 510 cartos but wanted to see what life expectancy would be in comparison to regular atty's? 
Any other thoughts, reviews or comments on them would be greatly appreciated!
I love my regular 510 atty's but would like to broaden my horizons. Should I try the 510 cartos?
Thanks for the advice!!!
