I have a petzl caritool on my weaver cougar saddle. It's ok, but you can tell it's a little flimsy and eventually is going to break.. I'm thinking about getting a transporter or shembiner. Transporter looks nice and has the clip for more security, but shembiner is definitely cheaper, and I like simple, well thought out designs like the shembiner. Any thoughts on comparing the two? Also, didn't the older shembiner have a circle molded into the bottom of it to hold a carabiner? Why did they get rid of that?
