STX Sync 3

The Arnold Palmer STX Sync 3 is a long putter, according to golfreview.com, built around a 48 inch shaft as reported by that same outlet. Both figures come from a single publication rather than from STX itself or from any verified spec sheet, so treat the length and the category as reported, not confirmed.

Community opinion on the Sync 3 splits along a familiar line for belly and long putters. Some praise how it sits flat on the ground at setup, and point to improved 3-4 footers and describe it as deadly from 12 feet in. Others found it took 3-4 rounds to get comfortable with the stance and grip, a reminder that a long putter asks something different of the user before it pays off. golfreview.com went further than most, calling it the best long putter I have ever hit, though that's one reviewer's word, not a house finding.

Against the rest of the Sync line, the record we hold here is thin. What's on file points to a long-putter build with a following among those willing to adjust to it, and a learning curve that some found worth the trouble and others didn't stick around long enough to judge.
