my buddy got one and loves it. Was riding a power pro in a 155mm. His sit bones sat perfectly on it, but the edges seemed to rub against the inside of his thighs pretty good, which was a noticeable issue for him. Tried the Arc which allowed him to have the 155mm to have the sit bone support, but didn't rub on his legs at all. He probably has 70 miles on it so far and no complaints. Was so confident with the difference that he sold his power saddle after 1 ride.
I rode it (Also on a power) and it wasn't bad, but I haven't had any issues with the edges effecting me. Just like everything else, its personal choice. If the edge of the power is an issue, it sounds like this is a great option.
