In reply to subseasniper: I use Phud. It is of a decent quality regarding durability, but it's not brilliant regarding cushioning the impact. So, I'd hardly convince myself to climb a roof higher than 2 meters above the Phud.
Actually, there are not many pads that are doing their job well, in my opinion.
I have tried the Ronin Air Pad by Flashed and...it feels like a rocket science applied comparing to the Alpkit Phud. I'm seriously considering to invest in the Ronin. It's easier (and cheaper) to get a proper pad than fix ankle injuries, I guess.
