I have a Zaza slider and am trying to find a good way to mount it to two tripod sticks. After several months of use, I am starting to cross thread the middle 3/8 hole. I really don't want to keep using the center hole, so I figure using the outside two will make it a little more sturdy anyways. I'd like to Not have to thread a tripod through every time I use the thing, so I'm looking maybe for a cheap tripod head with a small square quick release plate (501/701 plates don't work) that I can just leave permanantly attached to the two outside holes. The plate would need to have a 3/8screw, and the tripod head bottom would need a 3/8 female hole. Any suggestions for me?
