@Shadowscape, you make some mighty strong statements on climbing devices used in SRT systems, and yet you claim to only climb this way 'occasionally' or 'as needed'.
The tools and systems a climber prefers are as diverse as the trees we work on and the conditions the trees grow in. It should be expected that not all tools or systems can excel when conditions and requirements change so much.
To say a tool is 'crap' because it does not work for 'you' is an opinion based on very limited parameters. For the many climbers that climb SRT on a daily basis, myself included, those 'crap' devices work fantastically and are the best choice for their needs.
