OK I understand with the shank but if all it's doing is the finish pass like what your showing then you could easily go well past the recommended feed rate as the WOC/DOC is so tiny. There is hardly any tool pressure on it so it's not likely to break.!
Regards the Slot then I'd Cam that up as a separate feature because what's the point of slowing the whole job just for that one area where you need to be careful.?

Recommendations are ok but you have to assess to each job and I can see that your slowing the job down and probably getting a worse finish because of it due to running too slow. Will be worth you experimenting with Feeds and slightly different strategies for areas like slots etc.

The video is actually the roughing cut and at the speeds and feeds I am using I get a good enough finish that I don't bother with a finishing cut.

The reason I am machining the slot and the blend radius is in places the radius is too deep to cut with a standard cutter. What I do is cut as close to the slot as I can with a standard cutter then finish the blend radius while I am cutting the slot.

I have been quite suprised how much these extended cutters will bend before they snap.
