("Larger sensors"??). The slightly slower speed really doesn't bother me, as long as the optics are good. Looking forward to seeing your latest image.

I still get a bit of coma with my f6 in the corners
Yes I read that info on the f6 Bintel newt 4 years ago ( ignored it ) I’ve even won a Bintel image of the month in Oct 2019 with my 6”f6 Bintel newt
The only modification I made to mine when I bought it 4 years ago was I added a dual speed focuser ( a must for AP ) don’t know if it comes with dual doors now ? And the second mod was fitting new heavy duty locally made Primary mirror springs after a year to make Collimation easier and hold Collimation longer
Cheers
