Is your source HD and if it isn't is there a really good reason to upscale it that much?
The reason your probably wanting to use maa and warpsharp is probably because of what your doing to it by upscaling if anything, they would go after it.
If it is HD then I would just take awarpsharp and maa out cause your more than likely doing more harm than good, HD sources are very detail oriented you would probably be fine with just the deinterlacing, cropping, and resizing and maybe gradfun if the shaded/darker scenes have the banding like in the case of my HOTD blu-rays. Just my opinion anyway.
"The people cannot be [...] always, well informed. The part which is wrong will be discontented, in proportion to [...] the facts they misconceive. If they remain quiet under such misconceptions, it is lethargy, the forerunner of death to public liberty. What country can preserve its liberties, if it's rulers are not warned [...] that this people preserve the spirit of resistance? The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants."-Thomas Jefferson
