They may look like summit...but they aren't! I stood on one yesterday at a 3D shoot, and I wasn't as confident in it as my summit as the platform was alittle smaller. I'm a big guy, so need all the platform I can get. Also, the one thing that these don't have is the rapid climb stirrups like Summit has, which makes climbing WAY easier. Loggy makes a decent stand, but Summit is the leader in climbers.
