I put a 22 lb flywheel on my FE and it revs very quick but drives easy in traffic. When I first put it on the road and before I was accustomed to the shift linkage yet, I made several 3rd gear starts by mistake and it just took off with little more effort than 1st gear. I suspect what will work best for you is something in the middle of the two extremes.
Also - I'm not familiar with SB Fords, but my slave cylinder mounts to the engine block on my FE. Is there not a similar option for the SB Ford? As often as hydraulic slave cylinders seem to fail - the thought of having to pull a transmission to replace a hydraulic TO bearing would not sit well with me.

The flywheels that are described as "lightweight" for SBFs are around 11kg or 24 pounds, and that's what I will be using. These are very light cars with impressive power-to-weight ratios (no matter what engine you're using), so no need for heavier flywheel than that, and I think a lighter one - for my purpose - will not suit my driving.
As far as clutch slaves go, my tunnel shape does not allow a clutch fork (the bonus is better footwell space
), so I have to use an internal hydraulic throw out bearing. Now that I know a bit more about them and how they are fitted, I'm quite happy about using one. Reliability when using a known brand should not be a problem. I don't know for sure, but probably all or most 'moderns' with a manual transmission would be using HTOBs.
