Finally got my mantis after about a year of research and watching tons of youtube videos. I think this is the most excited i have been for the upcoming season in a long time. I have practiced at ground level 5 or 6 times but the first time at 20 feet I used my tether and linesman belt to tether to the tree... lol. Just looked at the rope and thought what if... which I am sure with more practice I will be more comfortable.
