You really think so, manus have for years gave up GPU's and CPU's that are in middle and top range specs, with nearly or same hardware, only limited by copper bridges and/or firmware.
Drives and media could be the same, if you find 8x media that works flawlessly for you then burn at 16x.
You dont speak for NIL or anyone thats sad he pulled out the game.
The media is that cheap to buy, you can afford to test out at 16x to see what works for you.
If NIL reads this and hacks the 1.40FW tomorrow and puts up on a site, i will dl it and flash my 109 and be back to 16x on my choosen brand of 8x dvd-r.
