I added the megalith handles to my Crandell Jammer arms and I must say the addition has been a game changer. The handles are excellent quality and craftsmanship. The added range of motion removes the majority of pressure off of you wrists. My one recommendation is to go lighter than normal when you start because most of us have been use to static handles and your positioning with the megaliths will be a little different.
Perfectly crafted. Smooth threading and the grip is top notch. I had a concern over the protective washer not attaching securely but it's solid. Will definitely be back for more if I need more!
