I have a manual thumb for my machine, I like it better than hyd because it is a little quicker & easier to take off the machine. I know that you can fold up a hyd thumb(seems to get them almost out of the way), but the weight is still there, and that cuts back on your bucket size, so I would rather just take it off when i'm not useing it. Now if somebody made a quick coupler for a hyd thumb, that would be really slick.
