On Work Position.

I often hear climbers champion Single Rope Technique, claiming that they couldn't imagine working a tree any other way. I agree with this, because I mostly climb utilizing SRT for most of my work positioning.
When I started climbing I learned on a traditional dynamic system. For me, the biggest problems with this technique were: ascending, managing friction and retrieving my friction management device. Naturally, SRT answers the problematic questions that DRT posed for me.
I think that SRT also owes itself to the production climber because of some of the steps that it eliminates when setting up a tree. When basal-anchoring, there's no need for limb isolation, just a suitable suspension point to carry the load. I can set two primary lines basal anchored in the time it would take to isolate one limb in a DRT configuration (not to mention the pain of sending up a ring and ring). In the same respect, there's no secondary gear retrieval (ie. a friction management device), only rope to pull when the climb is complete. The 1:1 movement along the system as compared with  that of 2:1 in DRT is also a favorable case in point. Of course, these are the obvious characteristics when we're comparing these two climbing systems. I don't want to beat a dead horse.
I don't want to get into the load forces that each system presents either, as that could be a whole discussion in itself that I'll save for another time. Let's assume for this article that the suspension point is strong and can either carry a basal anchored system which would exert twice the load when compared to that of a canopy anchored system.
What I do want to get into is what I call exposure. I'm going to define it, and then I'm going to talk about why an SRT system lends itself to mitigating exposure for the climber in a very effective way. Let's imagine a broad tree with no one central anchor to access the entire crown. Decurrent in character if you will. As a climber crosses over the center of the crown while anchored on the opposite side, rope angle begins to flatten. The potential for a dangerous swing increases. This is exposure, and it has everything to do with rope angle, and the distance to your anchor, and not beng lanyarded to the tree. In order to mitigate this exposure, the climber must change their rope angle. This is for me, the biggest benefit of an SRT system verses a DRT system.
When the climber redirects the climb line in an SRT system, the rope is static, so there's no friction other than that on the climbing device. When redirecting a DRT system, more friction must be managed. This is the deal breaker for me, the re-direct. It has the most DIRECT effect on achieving a comfortable, non-exposed work position.
Remember the broad tree with no central anchor I mentioned a paragraph ago? Well, your on the far side of the tree, far away from your anchor, your climbing higher and higher and the rope angle is getting dangerous. Instead of taking a selfie, you decide that maybe you should mitigate your exposure. For the SRT climber, you can install a simple false-crotch redirect, or drop your climbing system through a natural crotch redirect. Done. The DRT climber runs into a problem, they either can install a fancy redirect with pulleys and other gear that makes an attempt to manage the friction introduced, or they can retrieve their original anchor and reset all together. Meanwhile, the SRT climber has already updated Instagram and called for rigging.
When I study all the hype around the discussion of SRT verses DRT; it always comes down to this one simple concept of being able to easily change my rope angle in an SRT system. My biggest fear in canopy access is exposure. In big crowns I think it's a very real danger. Changing my rope angle diminishes the anxiety that bad rope angle creates. This leads to a safer and more comfortable climb all the time. And that's really why SRT is awesome.
