Ordered 150' of Samson Pro-Master 3 Strand 1/2" rigging rope. Heard about the exceptional customer service from TreeStuff.com and when order didn't show shipped in two days I called and was told back order. Asked when the Pro-Master was coming in and she put me on hold. Came back and said for your trouble choose any rope as a replacement and we will get it right out. Went with the Tree-Master that is just a bit stiffer but 100% Polyester as opposed Poly Olefin middle in Pro-Master. They had a free shipping coupon on their website and the Tree Master is twice the price of the Pro-Master so think I made out and can vouch for excellent customer service. 150' of Tree-Master 1/2" 3 strand with free shipping for $51. Any thoughts on Tree-Master versus Pro-Master? By the way intend to use it with my Maasdam Rope Power Puller.
