I think so.Greg Griffin said:Fins sized for a placement that gives you the same sweat spot as a great thruster .
Large system fins can't be placed there - need to be created for that and were 30 years ago .
10 years before FCS took over production of all boards in the mid 90's with no twin fins or 4 fins to offer .
Hope that gives you some insight .
Do you mean, that because of the fin box size, it's impossible to get the fin close enough to the rail?
Take this one for example (the one I'm interested in). https://www.jsindustries.com/black-baron. . I know it's hard to tell from pics, but in your estimation, the fin placement's not as good as it can be, because of the FCS box?
