Just a quick update. I went to ISE in San Mateo yesterday with junior in tow. Looks like quite a few vendors have pulled out, especially guide services. The show was condensed down into 2 halls (one big, one small) and even those weren't totally full. I'm hearing rumors from folks I know working various booths that this may very well be the last year for ISE in San Mateo. I'm also told that most of the vendors not present in San Mateo will be at the Sacramento (Cal Expo) show, so that's a small glimmer of hope.
I did check out these UltraFlex Slings and thought they were pretty slick. I'm planning to get at least one, since the owner was demonstrating with a Remington 700 and the overall fit and feel was outstanding.
