Attaching specific bone to component

Hello, I would like to grab a skeletal mesh. My skeletal mesh is a rope build with 30 bones. I want to grab my rope in this the point Im line tracing. Im looking for a bone name. I tried to use Physics Hande and it works, but there is a delay between grabbed obj and my component (eg. hand) when Im moving my mouse. In this case im trying to use AttachToComponent method because there is no delay. And it works with a static mesh. I cant make it work with rope. Attached component need to have simulating physics turned off. But I cant turn off simulating physics in my rope, because it wont be a rope anymore. I found a very useful command SetAllBodiesBellowSimulatePhysics, but eg. when Im line trace in the middle of the rope, the half of the rope will behave like a rope and half will be stiff. If anyone could help me with this problem, I will be very glad, I can post some screenshots or paint or write more explanation. Thank yo very much…
