Good advice from Stephen on the Maasdam, you don't normally need a lot of rope with it. Using a prussic is great but you can also just tie a bowline on a bite or a double bowline in your pull line and hook your Maasdam's hook into that. It's a cheap and good investment. I've also pulled my truck out of mud holes and sand beds with it a few times. Don't know how it would work with your rig, but when limb walking SRT with the HH you can attach a hand ascender or prussic with a carabiner on your climb line above the limb your going out on, clip the tail of your climb line in the 'biner and then back through another on your saddle. Gives you mechanical advantage coming back in. I think Nick Bonner's got a vid on that somewhere.Also for the advice on the the maasdam, got some other stuff to pick up first, definitely on the list though, I'm not really doing the big monster trees yet, so I've some time before I see one being necessary in the future. Also, I've been climbing SRT for a couple weeks now, started with the petzl rig, but really didn't like going limbwalking with it as you've got to use both hands for your rig.
