I understood that this was a problem that always happens with the OP. If you learn a weave one way (say as a childhood trick) it is always much more difficult for you to make the weave again using a different method (or without using your hands, or whatever). This is why Avi has so much trouble with gateways, it's a slightly different weave to here instinctive one.
In general, I consider things like Travelling and Healing to not be proper Talents as they're just weaves, whereas things like Dreamwalking, Foretelling , seeing ta'veren and such which are not so mush related to the OP as Talents. I do remember that AS talk about Healing being a Talent, but I feel it's likely that they have their terms mixed up because they're too focussed on the OP as the only possible source of "supernatural" powers.
