Okay guys so I just put in an order for a Mantis and plan on using sterling 9mm HTP for both my tether and linemens belt. I was going to also go with a kong duck for both. My question is is it worth getting sewn eyes? I think I'm definitely going to get at least one on my tree tether for sure. But for a backup loop to clip in the carbiner would just a figure 8 due? What about for the linemens belt? How much bulk is it going to add?
