I've seen lots of mixed reviews on the 120XP, mostly complaints about high backdrag. The head also looks pretty massive on them compared to others.
Is there anything other than tooth count that makes the 120XP an upgrade on the 84T GW? If anything the majority of advice I've gotten is the 84T is the nicer, smoother ratchet and the 120XP is tooth count bragging rights. But I have no first hand experience with either.
120xp "high backdrag" is one of the
GJ myths I have yet to figure out.
I took a video to show the sounds of turning Snap On, 120XP, 84T, and Carlyle 90T, side by side.
The smoothest, quietest, lightest is: Snap On
Carlyle 90T and 120XP are similar in terms of how easy to turn (low backdrag). However, Carlyle has this loud "clunky" sound similar to all single paw Taiwan 72T ratchets.
Gearwrench 84T is the least smooth, loud and clunky.
I'll figure out a way to test the backdrag. I expect the result will show that 84T actually has larger backdrag.
I don't know what goes wrong here. The 120xp backdrag "issue" often mentioned here is totally opposite, which is amazing.
120XP is actually 60 teeth with 120 positions, not exactly tooth count bragging.
