RE: summit viper or tree lounger?
Not a big fan of summit stands but would take one over the treelounge. Look at Timbertall...Ol'Man or Lone Wolf Alpha Sit and Climber. Your supposed to be quiet going up a tree if you plan on shooting anything worthwhile a Treelounge is too noisy and on the right bark the new Model will kill you. Old Treelounges were extremely safe but still noisy and very heavy.
