The separation of throttles is huge for me in that each throttle now has way more throw in the actual physical limit of how far it can be depressed. Thumbwheel and single triggers split that one motion into two controls and I found myself always tweaking settings to make it feel “right”
Thumbwheel remotes are often pretty unintuitive when it comes to forward vs reverse direction on the wheel. At least the trigger ones are intuitively pulling “in” to a home position WRT the remote main body. Even then, if I get some speed wobbles and relax my grip, I can throw it too far and hit braking dependent on remote size, hand size, trigger size, glove usage etc. I will never accidentally brake or accidentally throttle from a finger moving in the wrong way on a split trigger. Both triggers pull in opposite directions, independently of each other, with no way to lock up my fingers on it. Riding switch regularly really fucks with me mentally when the mindset “roll wheel forward to go forward” is no longer true.
I see what you are saying about remote grip but when I’m accelerating, my thumb is still holding the remote firmly. When I am braking, my trigger finger is still supporting the remote as well.
Crashing with a finger tucked into a trigger mechanism is awful. Natural instinct is to open your palms and brace. Thumbwheel, you usually just let go. Same with split trigger. I’ve used the maytech remote as a slide puck ~15 times and the fucker still just runs.
Most importantly: I’m a human factors engineer so things that are counterintuitive to human design/usage irk me. Single trigger remotes require extension of the index finger to brake. I don’t believe throttle is best controlled by the relaxing of muscles as you do not have the same resistance feedback mechanism. Flex action control is what is commonly used.
