In reply to Stamford Raffles:
> I need advice regarding aiders, fifi hooks too.
There are at least half a dozen methods varying from using 1 to 4 sets of aiders and either fixed or adjustable fifi hooks.
This is one area where buying a book or referring to in depth online articles is probably better than relying on forum posts. The US sites, supertopo etc. are your best bet but IIRC Planetfear had a good multi-part article on aid climbing. Also it is worth a look at Andy Kirkpatricks website, psychovertical.com if he ever gets it back up and running again.
