I don't know how important it is to you but a feature I use all the time on my old Diawa Autocast is the ability to flip the drag back on with the thumb bar. For this reason and this reason alone I decided not to get the Curado, or Trion when I was looking at reels a while ago. I ended up not buying anything at all yet. But when I do I will be seriously looking at the Shimano Castaic. One of the things I plan to do at the upcoming Sportsmans show is to look at reels to see what models have this ability. I use this when drifting gear to control the line going out.
