Mina climbed loads of hard problems, as did David, and we featured Mina's ascents in a few UKC News Items last November and December.

Now we have a set of nicely put together videos from David Mason, mainly featuring Mina, but with a few clips of David too.

If you're thinking of going bouldering in the USA (yes please!) then check out these videos that will be popping up on UKC over the course of the next few weeks.

• The first one was Joe's Valley highballs
• The second was Joe's Valley: Left Fork Classics
• The third was Joe's Valley: Right Fork Classics
• The fourth was New Joe's

Now we have Yosemite Highballs

Mina introduces this video:

"These problems are all pretty high but I had very different experiences on them. Flatline had a hard section at the bottom and then another hard bit right at the top. I flashed the bottom section and surprised myself by committing to the top section on the flash too. This was pretty unusual for me, I often want to scope out a highball more before going for it. That is what I did on Cindy, a similar height but a harder problem. I abseiled down the problem to feel the holds and try the top moves before going from the bottom unattached. Some may call that controversial but it is a lot more commonplace now and as long as honesty is maintained about the ascent that is all that matters in my opinion. Trying the moves helped my confidence and enabled me to try the beautiful highball more safely especially as it was slightly damp when we tried it!"
