It does puzzle me why is the concensus that flemish is faster (not that I know otherwise). Flemish is much more twisted than endless, so it's bound to have more mass per inch. It has more surface, and a non-smooth one (ie, less airodynamic).
I'm not an expert on strings by any means but here's a view from the cheap seats. Most of the string discussions pertain to Excals. For quite some time they have offered a FFF string. That stands for Flemish twist, Fast Flyte matl.
The reason FFF is faster than endless loop is the string matl doesn't stretch as much on the shot cycle, not due to the loop type.
It wasn't until the last year or so the custom string makers like "Boo" and a few others offered them for the public. Now, you can get virtually any thing from them and it's kinda blurred the basic differences in strings from what was once only simple mass produced choices from the factories in the past.
I take it you may be an engineer? Haven't you guys proved bumble bee's and helicopters can't actually fly?
