We use Goodrich external hoist with Bristow modification (arm etc. same as on RAF Griffin) on 412.
I believe adjusting low speed cam as suggested above and being a bit careful when coming to skid should suffice.
Years ago (and with old internal hoist config.) we had a situation where a rescuer was injured (arm injury) while passing by skid - and he tried to sue the crew! (didn`t work)
Limitation about hoisting in hover only is ridiculus. Probably result of some engineering ideas - like the one that used to be on EC 135, where NON ESS Bus failure stopped normal hoist operation, but thru battery bus hoist emergency power was still available - but limited to UP only!. (Not thinking that in such situation lowering load to the ground might be better option.)
Well, truth is also, that under certain combination of forward speeds and load types, an increasing swinging might occour - eventhough this speed will be generally above 30 KTS.
