Hi guys, thanks for the replies.
I have looked at the V1200, found images after I had that idea and it seems to me to be more of a long narrow scoop as opposed to concaving in the more traditional sense.
The "quint" gains 17mm in extra middle width but probably at the cost of a little extra weight. A lot also depends on the edge thickness.
The second image is based on the traditional shape but probably thicker than most actually were, probably could push the weight to a 4lb monster with a good dense cleft
I suppose the first image could be equated to the twin and four scoops and the third to the scoop in all their varying versions.
If I hadn't recently bought a bat (before I found this great forum
) then I might have commissioned a quinto, just to be a bit different
