newbie needs critique

[coils]

In the course of scouring these threads for info, I discovered Henriks Simetrix simulation for optimizing the sox/xsoz marriage.
I am not an experienced electronics engineer, and I am still ascending the learning curve in mosfet amplifer comprehension.

I have taken the liberty of using Henriks Simulation work for my own project. Thank you Henrik for making the original schematic.
My amp is still on paper, and I would like for some critical feedback from experienced designers on my plan before I make the amp. After I run my simulation, I don't know how to interperet the graphs. To view the file, requires Simetrix evaluation software and the irfp048 spice model from International Rectifiers webpage.

Thanks in advance for the help.
