Allow me to explain why I don't like forward clickies on multi-mode lights. It's only ever an issue when I'm on my bike, but that's my primary use for a light, so that's when it matters most.
When I switch on a forward clicky light, my first instinct is to full-click it on because most of my lights aren't multi-mode. That's great if the mode I want is the first mode, but if I want a different mode, I can't soft press to get there. It's wasted motion and a wasted click on a switch that wears out under normal use. It isn't optimal.
With a reverse clicky, I can turn the light on and soft press to my desired mode quickly and easily. This convenience, of course, means there is no momentary on functionality, but that doesn't matter to me.
With a twisty, I can soft press to my desired mode and then twist for constant on, or twist on, back off slightly, twist back on, etc. I typically use the latter method, because the primary advantage of a twisty
for me, though, is that the tailcap acts as a dashboard knob when the light is mounted to my handlebar. A knob is much faster and easier to locate and operate, especially with one hand off the bar, without looking compared to a clicky switch.
Off the bike, my most used multi-mode light has two switches, both of which must be on for the light to function. It has a forward clicky tailcap and a rotating dial near the bezel for mode selection (and off). I never use the tailcap switch; it stays clicked on. I just use the rotating switch. It's better than all of the above (for underhand use).
To be fair, there aren't many forward clicky switches that can handle that current, either. Fortunately, the LF drop-in the OP mentioned doesn't require such high current.
