Yes. Rogue axles sell the axle short on what it's truly good at doing. Two inches makes all the difference. I have abnormally large hands/long fingers for my height. Just as an idea, my hands are slightly larger than my friend who is 6'5". That said, I can touch my thumb to pinky just barely on a rogue axle and my thumb to ring on a 2 inch.
What's interesting is that my crushing grip strength isn't particularly strong at all. It's at average for someone my strength or slightly higher. What I do exceed at, is the ability to never let go of something in my hand, like a farmers walk. My upper back will fail before my grip does.
All in all, the hardest thing about the axle will be your ability to not yield to the harsh mechanics. A strong upper back and explosive ability, retained in the face of fatigue, like all things in strongman, is what makes you efficient at it.
