I can say with confidence that number of turns on the trigger coil definitely makes a difference. You should have as many as you can squeeze on your spool, but that depends if you have used a pre-made spool or made your own.
I have experimented with some alternative designs where trigger coil was wound next to a drive coil and trigger not having enough wounds made it so that the motor would barely work. It would actually work when the coil is facing the opposite direction (drive coil towards the rotor instead of the trigger coil).
With n-filar power coils, I have tried parallel and serial. Parallel would give me far smaller voltage spikes than serial yet everyone seems to say that parallel is the way to go (at least it is when you are making a multi transistor power setup where each coil wind gets a transistor).
I have tried winding n-filar and also power over the trigger+drive; n-filar is when you wind three or more (pre-twisted) strands simultaneously (for example trigger, drive and one power).
Alternative design that I'm playing with now has a trigger+drive wound first (26 + 24 AWG), then on top of that three-filar (20 AWG) power as many winds as possible to fit. When connected in series the power winds give me over 400V spikes, while in parallel I get about 150V+.
These are just some of my observations, best way to learn is to try yourself. JB is right when he says that people in general have stopped experimenting. They simple do what they are told (put this here and that there and it's done) by our conventional science that "knows it all".
