SRT or DRT

But this is recreational tree climbing.

Lichen,

I like the message of your posting. In the very beginning, I had hoped to do body thrusting as part of my RTC routine. I wanted the calorie burn.

By design, I'm a knots on rope DdRT climber. Eventually I'll expand gear and techniques. Right now, I'm getting the experience that I always wanted.

Another cool rope? What is the mm. sizing? Anyone know about this?

I see this completely, I suppose to ad a wrinkle here; I'll most likely be doing some canopy research as well. Where efficient canopy access is critical for field season logistics. I'd love to do field work all year, but there's that whole teaching part to getting a TA ride to grad school (and I can't teach intro biology from the treetops, however amazing that would be) So, can you still be quick with DdRT and take your time when needed?

In my experience, SRT is more efficient for straight ascents, while DdRT is better for moving around in the canopy. However, there is no reason why you can't use both techniques on the same climb, and with the same rope. Use SRT to ascend to your tie in point (or wherever you're trying to get to), and then lanyard in and switch over to your DdRT system. Either system works well for descending.

I was reading today the Treebuzz board and saw a discussion very similar to the one we had a while back here. Check it out

SRT is clear enough

You climb a single leg of one rope.

You climb/use two different ropes each of which has its own anchor point.

If I toss my rope over a limb, fasten one end of (terminate) it to myself and footlock the tail, that mechanism/process is to be indicated by which acronym?

DdRT, because the rope is doubled over a tie-in point and you are using both legs of the rope. More precisely a dynamic DdRT because the two legs of rope are moving.

If I toss my rope over a limb and footlock both ends as one, in the exact same way as for an SRT, that process/mechanism is to be indicated by which acronym?

Again, DdRT because the rope is doubled over a tie-in point and you are using both legs of the rope. More precisely a static DdRT because the two legs of rope are (relatively) stationary as you climb, i.e. they don't move up or down as in your previous example.

The difference is DRT = double rope technique, two ropes; and DdRT = doubled rope technique, one rope doubled over a tie-in point and the climber uses both legs of the rope for climbing.

Final Commnent:
Just to clarify one more system.....climbing 1 leg of a line 'doubled' over a TIP/anchor, with the other leg tied off....SRT or DdRT?

Happy New Climbing Year!

SRT.

Happy New Year, all!!

SRT of course, but with twice the load on the anchor limb.

HAPPY NEW YEAR!!!, already.

I always use DRT no matter what the size of the tree 20-100 ft tall. Depending on the size of the tree I used defferent devices to enter the tree. For small trees I use a handled ascender, which works quite well. But for tall trees I use a prusik knot with a micro-accender to automatically advance my rope in combination with a foot ascender. You just walk up the line.
