Hey, I'm sorry brother, but we actually try to stay away from threads that don't actually have any Harm Reduction value. I'm not belittling or minimizing the importance of what you're trying to do, it's just a matter of what we are and what we are not. If you need help regarding safety or Harm Reduction, we will be here to help.
What you need to do is try using them separately and decide for yourself. If we had 25 people respond to this, you would get 25 different answers of wild variability. There's no reason why you can't try it out for yourself. That's truly the best way to discover your own preferences.
