My thoughts:https://saddlehunter.com/community/index.php?threads/bolt-climb-video.9379/
It is definitely not the fastest way up a tree, but it has a lot of advantages, and it isnt as slow as you might think.
Pros:
Small and light
Easy and secure/safe/stable
Fast enough
Quiet
Stealthy/unobtrusive
Works on most any huntable tree
Usable for run/gun and single season presets
Cons
Penetrates tree
Lineman belt dance
Certain trees (soft, loose grain for example doesn't grip the screw portion of the ezkut bit adequately):suck to drill
More climbing time and effort than fastest methods on first climb
Presets need to be redone every year if pulling bolts
Any faster method is either less universal or significantly bulkier/heavier. If they're acceptable they're a great option. I prefer over everything I've tried except possibly srt which has a different set of advantages/drawbacks (less universal for run/gun, non penetrating, no lineman belt hassle, bulkier but still compact, presets can be longer term)
