I use the low-stretch materials on everything except my bows from the 50's. Those tips aren't designed for it (not properly shaped).
My favorite is TS-1. Much lower stretch than dacron, and a little less stretch than a quality linen string. It's more expensive than dacron, but it's thinner and stronger, so you can use fewer strands and even if you don't the string is still lighter.
Even if the bow wasn't faster with the low stretch strings, I'd still use them. Less handshock on every bow I've tried them on, more durable and resistent to abrasion, quieter on everything except one recurve I tried. On selfbows there's the added bonus that you're not getting smacked in the wrist with every shot (like you do with dacron).
The only thing you really need to do to make a bow "FF ready" is to shape the string grooves properly. A nice teardrop shape with no corners or other stress risers.
I usually gain 5-7 fps when switching from a good dacron string to a good low-stretch string. Guys will tell you that's not a lot, but it's the equivalent of shooting a bow that's 5-7# heavier! Those kinds of gains are well worth it in my mind, especially with selfbows.
