There are a lot of guys here who SRT climb so I know it can be done. However, I'll share my experiences with SRT. As with any personal experiences, individual mileage my vary.
My first season saddle hunting I was determined I was going to SRT as my primary climbing method. The SRT climb is really very non-strenuous. It may honestly be the easiest method to ascend a tree short of an elevator. In addition I really liked the idea that all I needed to carry was a throw ball and some string in addition to my climbing gear. I spent all summer working with the throw ball and practicing SRT on a tree in my backyard. I was sure this was going to be my go to.
Then came season and I soon discovered, at least where I hunt, there's a ton of knee high brush that wants to catch and tangle up the throw ball string as I attempt to pitch it over a branch. Add to that I found I had trouble finding trees that were throw ball friendly (too many or no branches where I needed them or too high to throw to). I found that what worked great on my nicely mowed lawn and tree in the back yard didn't translate into practical application in the woods, at least for the way I wanted to hunt. If I were intending to hunt from a preset spot where I could leave a pull up string attached it would be great. However, I rarely hunt the same tree twice during the course of a season so for me it was impractical. I ended up trying several climbing methods always attached to the tree with my rappel rope as my tether.
Eventually I found one sticking and have used that since. It's only been in the past coupe of years I have begun to climb and hunt on a short tether and only break out my long rope at the end of the hunt to rappel. It just works better for me that way.
