Grateful for your recommendations of best all-round mat for run-of-the mill bouldering, please (Roaches Skyline, Stanage Plantation, etc - no padding-out of extreme/silly placements). Most important criterion is excellent shock absorbance to protect my dicky joints, followed by no weak spot at fold, followed by wieldiness/ease of carry, especially with sac on. Large area least important.
Many thanks for your help,
Gary
