Tried the trans trigger. I have bigger hands and it was not comfortable in my hand at all. I know a few left handed guys could not get comfortable on it.
I tried a design similar to one of the shoot the light designs. It was a trigger style T-handle. Pushed it in to set and then pulled it to release. Was not a bad choice.
Also have a pressure sensitive button that is adjustable. It was a pretty cool button to use but was inconsistent as all hell.
To this day, I stick with the small metal mushroom button.
