I'm not sure about these moves opex is proposing for Black. How about this for a double-approach?

Also, the following moves for Black seem very good:
$$Wcm24 Captures: b - 1, w - 6.

In this position, Black might even be preferable. Sure, White got a big corner and captured some stones, but Black has a big corner, large moyos on the right and top sides, and more influence over much of the board than White. White's stones are just way too overconcentrated. What do other spectators think?

Does Black need to win the ko twice? What about this move for Black?

seemed too small a threat (and
correct to take). Maybe this is better for B?

So, a double high approach. The most severe kind of double approaches, according to senseis library.
I've found two josekis for this case.

This is peaceful. Immediate tiny life in the corner. Advantages: i may tenuki. Disadvantages: black gets enormous influence on both sides.

This
is the first instinct when i see hazama tobi. It allows me not to be sealed in the corner, build a tiny wall, and develop top left hoshi. As a drawback, it allows black to grab the lower side if he wants to.

This seems to be more of a right direction considering lower right. On the other hand, this may lead to a running battle which i'm not very good at. And i'm not sure how to answer
. And look at the top left hoshi stone: it is sad, facing black stones in both directions.
I'm inclined towards the second diagram. It may develop into a running battle if black somehow pulls out the lone stone near my miniwall, since the miniwall has ears but not eyes; during this running black may get the bottom, but i might manage to build some moyo on the top... And it keeps invasions i'm thinking of: at r11 and at m3... I rarely invade, preferring to make opponents invade my moyos, so i'm wondering: how will they go?.. Will i have a chance? Are they necessary at all? They seem early now since we still have space to grab, at the top for example. But if you look at my lower right strength, these moves look like attacking moves utilizing this strength rather than invasions. I don't know how to call them.
