11SIX24 Power 2 Ultre vs Ronbus Quanta R4
The 11SIX24 Power 2 Ultre and the Ronbus Quanta R4 are both 16 mm hybrid paddles, so this one comes down to the measured numbers. Across the 6 specs with a clearly better direction the Power 2 Ultre takes 5 and the Quanta R4 takes 1. The Quanta R4 swings lighter (105.0 vs 114.0) — quicker hands at the net, where the Power 2 Ultre plows through the ball instead. That is a preference, not a win. The Quanta R4 is $90.99 cheaper at $119.00.
Same shape and near-identical core thickness — a genuine either/or. Every number below is lab-measured, not a manufacturer claim.
