The Mind's Eye\nAre your putter's optics messing with your brain?\nA dual-axis alignment system on the Cleveland VP5 alerts players to a faulty setup: If you see the three white rings inside the clubhead's middle bar, your eyes are set too far outside or inside the ball. If the circles are invisible, your eyes are directly over the ball ($130, clevelandgolf.com).\nAre your putter's optics messing with your brain?\nThe dual-axis alignment of the VP3 Milled helps correct the position of the hands and eyes ($150, clevelandgolf.com).\nAll three staggered alignment discs on the Xcitour are individually machine-milled ($200, fussellputters.com).\nThe Black Carbon Series includes two blade-like models with a glare-reducing black-chrome finish ($250, mizunousa.com).\nThe vertically cut notch of the TwoBar Hybrid Blade works with a sightline to optimize aim ($200, rifeputters.com).\nThe company's signature black-on-gray color blocks (milled 304 stainless steel) are designed to help you line up the putter squarely ($230, pinggolf.com).\nThe green grip, shaft and clubhead on on the IC 20-20 are designed to optically melt into the background of the putting surface and emphasize the white alignment aid on the top of the putterhead ($140, nikegolf.com).\nThe aiming lines assist with setup, and the White Hot XG insert has a soft elastomer base for soft feel, plus a thin, textured outer layer for additional feedback ($170, odysseygolf.com).\nA precision-milled soft 1025 carbon-steel head with a nickel-plated finish has been fitted with tungsten "fangs" to move the putter's CG low and as far back as possible for a high MOI and better roll. ($270, odysseygolf.com).\nEverything on this putter is green -- the clubhead, the shaft and the grip -- except for the white alignment lines (one running the length of the blade, the other as an aiming line extending from the center of the face) that help you set up squarely to the ball. The idea is that because the green color tends to blend with the grass, the alignment aid becomes much more visible ($140, nikegolf.com).\nThe green putterhead and shaft of the 20-15A are designed to blend with the putting surface, helping users focus on the white aiming features ($140, nikegolf.com).\nThe series includes two blade-like models, the #1 (a classic Anser style) and the #9 (the half-mallet look preferred by Phil Mickelson).

($170, odysseygolf.com).\nOrange appears at the heel or toe if your eyes aren't directly over the Profound Ingenieur Blade ($480, profoundputters.com).\nBy placing a set of bars directly above two orange lines on the bottom part of the black putter, Profound has created a high-contrast 3-D alignment system to help you set up correctly, with your eyes parallel to the target line and over the ball. The milled-steel face is backed by a soft insert ($190, profoundputters.com).\nThe m2's optical aid (a small red dot on the heel side of the blade) is designed to be hidden by the shaft when the putter is addressed square to the line ($325, seemore.com).\nThis milled update of the original SeeMore putter has "rifle-scope technology" that helps players use their eyes to set up in the correct position over the ball. The alignment system is designed to help you execute a proper pendulum stroke by hiding the red dot behind the shaft at address and throughout the stroke ($325).\nSeeMore has taken its popular rifle-scope alignment system (which encourages the golfer to set up squarely to the target by making sure the red dot behind the shaft is hidden at address and during the stroke) and married it with the latest materials and designs ($325, seemore.com).\nA reverse-trapezoid shape places weight toward the back and into the corners behind the small putterface for a high MOI ($180, taylormadegolf.com).\nIn addition to high-MOI features, such as enormous volume, and a variety of alignment guides, the Spider's primary attribute is the "anti skid groove system insert."

($250, yesgolf.com)\nRDE stands for "reduced dimple error." It refers to the hairline ridges in the face that are designed to minimize the amount of contact area. This helps reduce the possibility of the putter catching the edge of a dimple, which might send the ball rolling off-line ($275, zenoracle.co.uk).\nThe lines in the face of the milled stainless-steel RDE Mallet might look like grooves, but don't call them that -- they're "micro ridges" designed to reduce the surface area that's in contact with the ball at impact. The purpose is to eliminate inconsistent roll because of off-center dimple contact ($325, zenoracle.co.uk).
