We got to practice overhanging, traversing aid climbing. And cleaning the same - which is quite a job. We also did aid climbing on gear. BTW, if you want to feel confident in placing trad gear, aid climbing is a great way to go.

Aid Climbing At VEM
Yesterday, the weather was too nice to be outdoors, so Peter O. & I headed for VEM. Luckily, most climbers had ignored my plea to only climb indoors, so it was very quiet.

Use The Rope To Tie Into Anchors
Testing the strength of falling directly onto slings, is a good reminder that your PAS/daisy chain is great if you're going to keep it tight at all times. Attaching your rope to a Master Point made with slings, is a good way to absorb falling forces. It also appears that clove hitches and overhand knots absorb the forces too. And nylon absorbs forces more than Dyneema. (Watch the video at the link for a detailed explanation.)
"Carrying out a final test replacing the slings with 8.2 mm rope for a worst-case scenario with a fall-factor two clearly showed – as expected – that utilising the shock absorbing properties of your rope dramatically lessens the impact forces on the anchors and is the best option. This could be by either clipping the anchors directly with the rope or into a central point in the system. For a full explanation and examination of the results watch the video...The results show how very high forces can easily be generated using slings to attach to anchor points if there is slack in the system. Clearly, it’s important to be aware of this if for example, you are moving around at a stance while clipped into an anchor using a sling or rigging a multi-pitch abseil. For perspective, most leader falls are between 4 – 7 kNs. Forces above 10kN may cause internal injuries – 10kN equates to 1 metric tonne."

Rappin' With A Skinny & A Fatty
I'm practicing rapping using a skinny tag line and a regular fatty lead rope. This is a 7mm and a 10mm. I had no problem rapping the regular way with an ATC. Just had to go a little slower. But, if you want to use an autoblock knot, you need at least one more wrap around the ropes.
Then I tried a single line rappel using a GriGri. I tied the fatty and the skinny together with 2 E.D.K.s (don't think 2 knots are even necessary) and clove hitched a big 'biner to the fatty as well as clipped that 'biner to the rap line. (Don't think it's even necessary to clip to the fatty.) When I got to the bottom, just pulled the skinny and voila. Both ropes pull easily. The big 'biner might get caught, so you have to be a little careful. But using a skinny instead of two fatties would save a lot of weight and space.

Longest Roof Climb
A Red Bull sponsored climb in the desert of Oman in a cave about 500' high. Look at the two climbers at the 4:07 mark to get an idea of scale.

Climb Indoors
Here's what happens when too many people want to climb outdoors:
" Nepalese climbing specialists will fix a second rope at the Hillary Step, a dangerous "death zone" bottleneck near the Mount Everest summit, to ease congestion on the world's highest mountain, a hiking group said on Thursday....
" Nepalese climbing specialists will fix a second rope at the Hillary Step, a dangerous "death zone" bottleneck near the Mount Everest summit, to ease congestion on the world's highest mountain, a hiking group said on Thursday....
Exhausted climbers have been forced to wait there for several hours, awaiting their turn to climb up or come down a single rope, exposed to risks of thin air in what is known as the 'death zone'."
It appears that most climbers are avoiding the "death zone" by climbing indoors.
“The outdoor-climbing market is not growing leaps and bounds,”Greg Thomsen, managing director for Adidas Outdoors toldOutside. “But gym climbing has a very strong growth rate. Something like 1,000 people a day are starting to sport climb, according to our research.”
At least when you're indoors waiting for a climb, you can get a quick snack.
