Just checked the official numbers on Joola’s and Xiom’s websites, and my assumption was confirmed:
Hugo HAL: 157 mm x 150 mm
Joola ARY-x: 157 mm x 152 mm
The blades weigh the same, but the larger head size means the HAL is heavier overall and is more head heavy.
I’ve played a few hours with the robot, and even though the blades weigh the same and both are lacquered and both have Stiga Helix Platinum XH/H, there are still several aspects that make a direct comparison difficult:
1: The rubbers are the same, but the ones on my HAL have been used for 1–2 months.
2: Even though the HAL is also lacquered, I think sweat, moisture, touch, minor damage, and general use over the past year will affect how it feels.
3: The different head size and overall weight
I’ve only played briefly with a robot so far, so I’ll wait to write a full review until I’ve spent more time with it.
For now, though, I’m really happy with the same feel and control as HAL but with a little more speed thanks to the larger head size.
My only concern is that I play quite close to the table with a lot of quick exchange rallies, and a heavier, head heavy blade might cause some challenges. I once tried the Xiom Hugo ALX Pro (160mm x 152mm), and it disrupted my game with a lot of edge hits and mis-hits.
The handle on the ARY-x is slightly wider than the one on the HAL. The HAL feels smoother, but that could just as well be because it’s been used for over a year.
