The custom send function of BlockChain.info does look pretty nice (I wasn't aware
of its CoinControl-like capability) and it's great that you can easily access it via Tor!
However, there are also 2 cons I can identify with it:
- change address:
while it allows some control over the change address, it doesn't support
specifying an arbitrary
change address, as far as I can see.
- I guess you do need to trust the Blockchain.info server not to spy / keep
usage data on you
However, I will test it some more as I do think it is very promising.
In the meantime, I have updated and rewritten large portions of my guide, and the
approach and ideas are presented in a more consistent way now.
