I will have to say the joe flipit can be tipped away so that you can get 100% bare flash in a matter of seconds. This way you can have full control. I use my flipit with the index card so that it acts as a gobo on shoe.
bounced flash top left corner and left wall aswell as ceiling. No direct flash on the baby. This is of coarse a situation where walls are close and low.
for outdoors I use bare flash. I see no point using a flipit outside. If you can bounce on anything I'll do that outdoors. If colour cast happens I correct in post.
I guess your intent is to get fill flash flash with flat light the lumiquest 80/20 will work. This is OK but its no where near as good as bouncing on a wall (left/right) so you can get dynamic looking photos with shadow cast. Sometimes landing the shot is what you need.
I wouldn't be shy to ramp up the ISO to help you out with the limited light you have.
