Back when i was fairly new to the game, I experimented with scaling too, thinking it would make my nose-bounce issues go away.
But the way I use my controls, my nose-bounce issues go away when I get rid of scaling. This is the third joystick (two Saiteks, but I don't remember the brand of the one I started with) that I've used these settings on, and had no issues. When the stick starts to spike, it's due to worn out parts (in my case anyway), so I just take it back and exchange it.
I flat-lined my scaling probably 5-6 years ago, and wouldn't go back. But keep in mind that I fly with a very delicate hand. To me, it's about fine-tuning my controls, which I can't do with the mushy-feeling (to me) scaling. When my stick is scaled, and I need a small correction, I apply it with the stick but don't quite get it because the scaling gives me less throw than I applied... In my case, that makes me give more control, and teaches me to give more than I need to get what I want. Effectively, I feel it teaches me to over-control. In a "stressful" condition, things get bad real quick, since not only am I yanking my nose all over the place trying to get my guns on, I'm killing my E in the process.
For my control style, I can't fly anywhere near as smoothly with a scaled stick, or shoot as well. Well, for general just flying around stuff I can, but not when things start to get nasty and I need the plane to do exactly what I tell it to do...
If you fly ham-fisted, getting rid of scaling will probably be problematic. Lots of people swear by different scaling strategies, and many of those guys are great sticks. Scaling is obviously working for them.
I'm kind of old-school though. IMO, if you fly ham-fisted, you should learn to stop! Control yourself! Camouflaging the problem with scaling doesn't make it go away.
I'm not saying getting rid of scaling will work for you, but it might be worth a try.
