As SRT goes, Fferna is nice and straightforward. I wouldn't like to do it on a rope without a jammer or something for safety, but even a Shunt would do. Or Prussic knot if you're into that sort of thing. I.e. you'd be doing it as a scramble but with some sort of a device to stop you if you start to slip.
Personally I find electron ladders to be evil buggers, best avoided.
I found that the best way to learn SRT was to join a group of experienced explorers, borrow kit for a couple of trips and just go for it. Starting with through trips that only involved abseils before moving on to ascents worked for me (followed by some proper training sessions).
If you can get to North Wales on a Thursday night, usually Blaenau or Bettws area, we'll be heading somewhere and are always happy to welcome a newbie or two. Check out the Aditnow forum for details. No SRT this Thursday (just cold, wet and miserable), but there will almost certainly be some next week.
