I was recently looking into splitting signal to buffers, that page has a great deal of info.
I am set that a jfet buffer is more appropriate for that function.
There is also a Vero design for splitting to 3 outputs which can be easily modified to add more.
So you need to add large electros to ground from the top row. 100u is pretty standard.
I don't think jfets are more appropriate than op-amps for buffers or splitters, but jfet splitters work fine too, with slightly lower output than the op-amp version. There is no power filtering or protection on that linked vero either, so you could add it the same way.
