e6k should I use fuel or ignition cut?
I know if I lean her out she might pop a vein but Iabsolutly cant stand how abrupt ignition cut feels. not to mention my tach goes berzerk and ****.
I read somewhere that some professional rotorheads like ReTed and a couple others had good success with incorporating fuel rev limiting rather than ignition.
I know the general concensus for rotary engines is never turn off or lean out the fuel, but this thread is more aimed for the reasoning why some pros choose fuel cut in favor of ig cut.

Fuel cut cuts all the fuel injectors off.
Very small chance you'll hit a lean spot that'll kill your engine.
It's also milder than an ignition cut.
Ignition cut is more violent.
You're also loading the exhaust system with all that gas.
When the ignition finally cuts back in, you could damage the exhaust with a huge backfire.
You can experiment with both types by setting them at a low RPM.
Try like 2,500 or 3000 RPM and rev in neutral.

i like the ignition cut better, it makes it easy to get rid of tailgaters 
seriously though, it seems like fuel cut could cause a lean spot if at full boost during the cutoff, especially if bouncing off redline for some reason. but then with ignition cut, could the backfires put stress on the engine seals from the returning pressure waves?
