My plan for this coming season was pre-sets and I was originally just going to use Cranfords but after seeing all the carbon fiber bolt talk on here I decided to order some. They came in the mail today so I took the bolts and my mantis out in the backyard and started drilling. Man once you get your tree prepped you absolutely cant beat a set of bolts. They fit anywhere and are ultra light. I get over 20ft in no time and to make the deal a little sweeter they make a great ring of steps. So my climbing method and ring of steps both fit in an SYS hauler. Glad I decided to get them after reading all the good info on here and plan on making them my only climbing method from now on when I have access to my pre set spots.
