If you want to climb, crag and swing in complete safety, opt for the OHM II from Edelrid!
This assisted braking resistance system increases rope friction when there is too great a weight difference between belayer and lead climber. Placed as a first sheath in the belay chain, the OHM II increases rope friction in the event of a fall, so that the belayer can support a heavier climber. As a result, the risk of a fall to the ground is significantly reduced, while the risk of burns to the belayer's hands is also reduced, and wear and tear on both sheaths and rope is reduced.
Recommended for a weight difference of 10-40 kg, this clever device will take a lot of stress off both climber and belayer!
