I do like hard rolls, but prefer a long mellow experience to a short sharp one. A pill I had recently had a very long come on - it took about 90 mins to reach its peak - and was about average strength and had a very long, gentle come down. I gotta say, in many ways that was my best pill. I think, like Melancholic said, that my preference has changed, although I can still get totally knocked off my feet by one strong pill - and that's fun too. Either way I try not to fight the experience, but just enjoy what I'm getting. That seems to be the most important bit :D
