your doing the right thing , asking questions.some of these responses you get,well you need take with a grain of salt.before i bought the xi5,i asked questions to.my favorite response was (the wind is its friend and great spot lock).And that is all true but,the wind doesn't always blow and that foot pedal,well its got spring tension.hard to navigate with it. it will go from right to left really quick.Theirs no in between .
