Do SCUBAPRO fins require a SCUBAPRO brand spring strap? I would prefer to buy spring straps from MBT if they are interchangable with the ones MBT carries. They are The fins are SCUBAPRO twin jets by the way. Any help appreaciated. I know my old tusa fin straps wouldent interchange with cressi, and none of the three will pair up with another, so just wondering.
