11SIX24 Power 2 Ultre vs Ronbus Quanta Pro R4

The 11SIX24 Power 2 Ultre and the Ronbus Quanta Pro 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 Pro R4 takes 1. The Quanta Pro R4 swings lighter (113.0 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 Pro R4 is $89.99 cheaper at $120.00.

Same shape and near-identical core thickness — a genuine either/or. Every number below is lab-measured, not a manufacturer claim.

Static weight 8.1 oz vs 7.9 oz — a few grams of tape moves swing weight far more than static weight, so either can be pushed toward the other.
