Can someone make a comparison of the two? Which one is better for singles? Doubles? Which one do you prefer and why?
Voltric 80 suits well in both singles and doubles. Mainly 3U is for singles and 2U is for doubles. Voltric 80 has harder smashing because of its head heaviness. 8DX is slightly head heavy, defense is better than Voltric 80 but it is more suitable to use for doubles.
Yeah. It should probably read "3u for singles, 4u for doubles" The Arc8dx is supposed to be extra stiff; not sure how well this works for most doubles players...
In general Arc8dx would be better for double because of faster swing speed and better defense. Voltric80 is better for single and more powerful smash but slower in defense.
