I'm debating on getting some these clamps for fence jigs, tapering jigs, add slots to my crosscut sled, and probably add slots to my outfeed table.

After doing some research there are two kids now: The regular dovetail clamp and the dovetail clamp AP. The AP is 8" and has a spring to keep it up and prevent it from sliding down.

I don't know if I need 8" of clamp room and if the clamp might get in the way. They are about $30 a clamp for the AP newer model and $20 for the regular 4" model.

What are you all using and do you like them?
