My pallet forks with single matching grapple is my best buy.
I like the single grapple better, because I can slide my forks closer together to pick up medium sized rocks and for other jobs where I need the forks together.
I've used a dedicated grapple a lot in the past and there's nothing my pallet forks/grapple won't do that the grapple can, and on top of that, the pallet forks will do a LOT more than a dedicated grapple.
I've probably posted a hundred pictures in the past, proving it. Mine is ALO brand...
