Both inexpensive solutions, can't go wrong trying one. The socks are pretty minimalist. Only way they could be less obtrusive is if they were open on the back or could be removed while climbing, but they're certainly more comfortable unless one of those is a really big deal to you. Might be less coverage, too, but they keep the very front of the leg covered and the rest isn't such a forward-facing surface (or as hard) as the shin bone. So when you catch the rock next to the pad it's more often a glancing blow. Which all seems like rationalizing less protection, but if you didn't go straight to the 7iDP's or similar then obviously you know the best pads are the ones you'll actually wear.
