The Frontier is rather expensive compared to the TSC brand at under $300. Go and look at several and decide which one you like.
With the Frontier brand I have never had to worry about adding weight to make it work good. It is very heavy.
The Frontier BB is made by Woods, so you might have another dealer option there.
There are plenty of discussions on these in the attachments forum also.
I would not go with any wider than the 48" BB with the 2210, but, probably could go with a 5' grader blade. You want to cover your tracks when grading. The grader blade you will most likely have it angled.
