Default Which diodes for SMPS

I'm struggeling to find diodes for the bridge for my smps.
It's a ESP Project 89 based design. He states 10A diodes minimum, but thats for a 300w PSU I think.

So far I've found these.

BYW29-200 7A 200V
BYW81P1-200 15A 200V (very expensive)
BYW51-150 8A 150V
BYW80-150 8A 150V

Would any/all/none of these work?

I plan on using a LM3886 based amp to drive two 40w pioneer 6x9 speakers and is worried about current.
