My slip neighbor had a problem with those long tang-type straps on his C30. When furling, there was so much play in the straps and pins they would rotate/twist in the process. He got a bar of ss, had it bent in a u shape to fit the clevis pin. Still some slack, but not as much. $$$If those straps don't raise the drum high enough, simply call Profurl with the length you desire and they will hook you up.
