An oversized grip for the "armlock market". Had tried SS many times, but to no avail. My only concern is immediate wear on the edges from in and out of the bag. Will be watching that.
Great product - the flat side against your arm is the difference maker.
Not really a flaw as a personal wish for this grip. Works great for arm-lock putting, it is over sized for a comfortable loose grip and the large flat surface allows for great awareness of the putter face. My only wish, and this is a personal opinion and might not work out in practice as well as I think it would in my head, is that the flat surface was more rounded at the bottom only the grip where my hand would be holding it. Maybe not round but maybe more like the top half of an octagon. That way it would still have the flat surface for locking against the arm and the hand would have a flat surface to keep awareness of the putter face but also the give a slightly more ergonomic area for the lead hand to grip the putter. Also a couple of notes to ponder for anybody thinking about switching to arm-lock style putting but haven't researched it fully just yet. Using an arm-lock grip will give your putter face a super extreme forward press and for most putters result in a negative loft at contact so you'll need one of two thing to happen. 1. If you're comfortable moving the ball way forward in your stance and can still strike the ball square then you're fine (unless you really want to putt with a negative loft). 2. If number 1 isn't something you can do then you'll need a putter with about 9° loft. As for me I just move the ball forward and so far love the arm-lock style and would recommend giving it a shot. Happy putting!
Perfect grip for arm lock putting
Black, white and silver color matches my Daddy Long Leg putter perfectly!
Size of the grip is perfect for arm lock. Like the look, feel and weight.
Very nice grip and design. Very nice feel for arm lock putting. Length is great!
Grip is really good for arm lock putting very stable grip
Put my armlock putter together three weeks ago & never looked back! Much more stability & consistency of stroke. Building an armlock is s little more involved to get the loft, lie & grip angle correct but we’ll worth it. Thanks so much to Jumbomax & also to Bryson for bringing this design to the forefront!
Love the way DeChambeau putts. Checked out his putter - got this 17” jumbo max grip for my 42” putter and whao, this is awesome. Suggest you hold the putter about 4” away from your body and watch the ball roll in the hole. If you are seriously looking to improve your putting - get this arm grip for your long putter.
Bought grip for an arm lock putter like Dechambeau....love the fit and feel...great grip!!
