We have a Manson Supreme, Rocna and a Mantus. Hands down the Mantus is the fastest setter, and has lots of surface area, but it does not fit our roller as well as the Rocna. The the Rocna is our primary and the Mantus & Spade are back ups (they both disassemble to stow easily). Performance wise the differences between Manson, Rocna and Mantus have been all very minimal. If the Mantus fit our roller better it would be our primary for sure.. A Fortress is our sterner..... With all these anchors, and their great performance (compared to the older stuff), we have no desire to seek alternatives.......
