Thanks for the replies.
I mulled over pulling the trigger on an EA Wicked Dual Lid Root grapple yesterday. But, I watched some videos and did some more thinking about it. My conclusion, I just don't see a big enough justification to have both types of grapples for the expense. I could change my mind though. I really love the 55 Wicked Root Rake Grapple. For my small tractor, it is a good size and weight, and it can fully clamp with little space inside. This is good for almost all the work I am doing, which is brush control.
My biggest conclusion from my experience and other's comments, it is good to have any grapple rather than no grapple, no matter what type it is.
