I've had a couple of pairs of Mago's. They are good on steep lime, but they are stiff and stay stiff without much 'feel', probably due to the plastic insert of whatever they have. The heel is good. I've switched back to 5.10 (blanco) for lime as I didn't get much 'feedback' from the Magos and don't actually find them that nice to climb in. They do wear well though. I've used the Mago on Grit, but I've also recently realised that Stealth C4 (on the Blancos, but not on 5.10 Velcros) seems to be significantly stickier on grit than Onxy. As to the Dragons, the heel is too shallow for me. Ppl seem to like the Sportiva Miura Velcro...
