A throw hook has made a huge difference for me. I use the dmm captain with 50 foot of rope and an hh2. Its only 50 foot of rope, I usually just let it hang and pull it thru what ever it needs to be pulled thru as needed. If I have a decent sized section where I don't need it, hang it up and come back to get it when you return from that section. But often times I have already trimmed the center on my way up and with the hook there is no need for a return from many sections. Just throw the hook to the next section and pull yourself over there in a straight line. Use ascenders if you can't just pull by hand. With the hh2 on it, you can work off of the hook in srt ( not as primary life support, positioning aid only as per dmm instructions, less than 24 kn rating, and common sence) and it can be switched out to a ddrt/mrs when you get to the hooked point for a return aid or whatever else. I suck at throwing it, but it still kicks ass. I'm very persistant, I just keep throwing it untill it gets where it needs to be.
