A further note for everyone, unless something drastically improves with being able to use a public key, such as BSGS, Kangaroo, etc., the 67, 68, and 69 wallets, are all easier reached (time wise) now versus 135.
The lower puzzles are now very risky ... Even if someone manages to crack one of them still they could be easily stolen.
It's better not to find a solution than get it and then get robbed right away.
