Mine is double thumbed and it is fairly strong. It was pretty similar to my Bounty Hunter Pearl just a touch longer and a little bit less on medium-heavy. But about the same on Medium down. That may be partially due to the strong layout though too....I think with a less flaring layout (depending on your release specs)something like a 60 x 2.25 x 30 would be more lengthy and probably fill the spot your looking for.
