Grapple recommendations

I want to buy a grapple for brush clearing and wanted to solicit recommendations regarding brand, size, style. It will be mounted on a Kubota SVL 90-2. I've been looking at a bunch of brands including CA, Anbo, MIE, HLA (in Canada). I've read on a tractor forum that smaller is better in that grubbing out stumps and roots is better with a smaller size whereas others have said to get one at least as wide as the machine. I'm also undecided on style clamshell vs bucket style. Opinions are appreciated. :)
