The gri gri is no problem on the 9.4 rope, but when rope soloing I use my 10.2 cos its my work rope.
And I even used it on the mates 8.6 with no problems at all, use care when lowering with the gri gri.
If I used my 9.4 on rope solo I would just use back up knots every now and then to guarantee the catch. |
