Sure I have. In many trees. On skinny bean poles, just for the hell of it? No. Why would I? Its called the law of averages. Why tempt fate? My understanding of the effects on the stem (one with little taper, none the less) from removing weight, or even adding weight.. Parallel loading in general I guess, dictates that I do everything I can do to avoid being solely connected to that tree. No one is saying you can't do it, or that the next one will break her leg.. But, push the odds long enough, and you'll get a jollylogger learning experience, in my opinion. Not that its worth much.
