Do the pin tail part of the swallow creates a drive that sacrifice looseness to the point of it being less manuevarable than a squash?
depends how wide your squash is.
for a tail the same width a squash will release more.
Not enough information to make a call. Fin set up rocker and a number of other facters come into play. If everything else is the same the squash might have a tad more release.
Id agree, more release in a squash,
