I think I'd have to go with Hide here, even though Hide was a smaller heavyweight he could really punch.. Herbie had legit power, he had Riddick Bowe in some trouble in there fight and we know Bowe can take a shot (much better then Roy) This is no knock on Jones I just think he gets caught by Hide and knocked cold..
Hide was awkward and had a very erratic offense. I think Roy figures him out quick and begins to take him apart by the end of the third or fourth round. Jones stops him or wins by UD.
Jones would be a class and a bit above Hide at 200lbs. But whether that '200lbs' was legal is another question...
