The issue of limited options for bullhead pointwork can be overcome by using Marcway points and asking for the bullhead variants: http://www.marcway.net/list2.php?col=head&name=Marcway+00+%26+EM+Pointwork
I think they're built to order? Not cheap, but they look superb.
Also, here's a link to C&L's RTR bullhead track: http://www.finescale.org.uk/index.php?route=product/category&path=346_375_377_379
PS: Peco's bullhead uses code 75 rail, too.
