I was thinking about buying a large Robust Comfort Rest. I have never used one (or seen one in person) but it looks good to be able to keep your hand under the tool. Now I see that Nova modular rests look similar. I can not find the dimensions of the the top part of the rest itself. How do they compare? Is the nova rest as wide from top to bottom (not talking about the post) to get hand underneath. I currently have Oneway rests. Worth getting something new or not much of a difference really?

Thanks,
David
