I go back and forth. On one hand, it's nice to be able to get really really high if you want to, but on the other, tolerance is also sort of convenient. I never really have to worry about getting too high because my tolerance is such that I can basically consume cannabis all day and never really feel all that affected.
Everyone is different, though. I do take tolerance breaks from time to time, but I usually plan them out to coincide with trips I take to places where I am unable to acquire cannabis.
