Wow that is a hard one so many variables. It matters that one knows the environment ie. houses, power lines, dense forest etc. risk of failure.
First thing to remember is a cut tree is a commitment. So if you are not sure you are not safe!
Secondly it is not wise to trust holding wood in some cases.
That being said many techniques such as tall faces, installing the undercut pie into the corners of faces, cutting a second angle into the lower face and gunning a compensation into the lay may all be used. And yes a suitable bull rope and possibly tag lines may be required.
My suggestion would be to try to test these techniques in a safe environment and avoid the use of a Dutchman whenever possible. Not that they don't work they can work fine but are more unpredictable than other methods. The hing wood is put under greater pressure with the Dutchman and premature breakage does happen. Around homes and power control is paramount and ropes are almost always incorporated.
