Rudder still plays a part. Get a 152 down to below 150 mph or so and kick full right rudder in more or less level flight. I can make it depart flight pretty much on command doing this. I suggest doing this above 10k, because if the stall gets away from you it's going to take you that much air to get it back.
It slews hard sideways, then flat spins like a leaf. I used to pancake just off the end of the runway on final because of this every once in a while. Using left rudder, never had it happen.
Never figured out how to use a stall to advantage in the plane though. It seems like I've seen guys do something vaguely similar to the 109k torque roll at the top of a rope, but I've never looked that hard at it. I prefer using the fact that it does hammerhead very nicely with proper throttle control instead.

Rudder helps for sure, I'll have to try what your saying, my way to setting it in the stall is pretty instant, nose up right or left roll matching rudder then flick rudder and stick opposite way making sure to keep the nose up....pushing nose forward recovers it almost immediately...might have to ride it our for a little while the plane gets more airspeed but controls work a bit...just finding that sweet spot to keep it level with nose below horizon for speed.
But like you said...these stalls do nothing often happening in the worse moment when you' re reversing back in a scissor or something (How I found my way to produce the stall). Find it hard to believe someone could control it short of flying near level and very low speeds (66 TAS is the lowest I got it in one of these stalls, and it only dropped there for a split second)....only time that would be useful is in a low speed low alt reverse, but you don't have the alt to do it.....puzzles me some peoples paranoia with the TA152's stall and roll rate.
Junky my friend, you might wana get hold of M00t about this. I'm not sure where you can find him tho.
I doubt he ever used any sort of stall to turn fight with planes over and over....feel like people would catch on to that and kill him. My success comes from transferring energy states at the right moments....using my E to create angles and using their E against them (Like making a KI84 do high speed manuevers vs a 152....You might think a KI84 turns better, but not at that speed). But that isn't anything specific about the plane itself except for maneuvering speeds...it's all ACM in the end.
