I have a mantis and recently tried a flex and a phantom. I ordered the phantom. I like the linesmens loop construction and placement, I love the adjustable bridge, and the leg strap attachment points. I didn't find the adjustment channels on the bridge loops to work on either end of their extreme, but worked fine on the center ones, which did change how the saddle felt, so the concept worked. It was slightly more comfortable than my mantis. If comfort was the only factor I would have just stuck with the mantis, but the overall saddle improvements are what sold me.
Edit; After receiving my saddle in the mail I must redact my comment made above, "that the bridge adjustment didn't work on either end of their extreme". The adjustment balls on the bridge loops were only made so that they're are three adjustments, low, middle, and high. The bridge was not designed to allow adjustment outside of that range. My apologies for my ignorance. I should have waited to make my comments after I received the manufacturer's recommendation on safe, and as designed usage. To anyone trying to decide on a Phantom I stand behind all other comments made. I received my Phantom today and will be swinging from it shortly. I will make additional comments on my use of the Phantom as I gain more experience.
As I write this it becomes very clear to me that we all must be very careful in taking at face value the tips, tricks, reviews, and technical specifications on any gear and its usage that are posted here. We must do our own due diligence, because after all it's our ass hanging on it. Again, my apologies.
