I think comparing healing to traveling is inherently flawed. The healing weave is low power enough that even the weakest AS can use it. The Traveling weave on the otherhand can not be used my most AS alone. Isn't it strange that a weave that you claim doesn't relate to strength requires a channeler to be strong to even open one. One of the reasons this weave was lost in the first place is because many women could not use it because they weren't STRONG enough. Also as Ive said before the Healing weave is meant for a small injury and while those who designed it may have intended for it to be flexible it is the equivalent of a first aid kit. When post breaking AS were stuck with a first aid kit they learned how to use it for surgery and that is Talent but it doesn't mean Egwene and others are deficient. Using more specific weaves Egwene and others could probably do a much better job helping someone. Traveling however is a weave that has a very specific purposes and there is no mention of modulating it like the Yellow sister does to her Healing weave by any other channeler. Besides the affinity strength in Spirit aspect Ive mentioned previously it just stands to reason that those who are stronger will have larger Gateways for another reason. We have seen time and time again that stronger channelers can split their weaves the stronger they are the more weaves they can hold at once. Most AS can't even do two weaves at once let alone perform Egwene's little trick. That ability to do more than one thing at once is obviously tied to strength and more importantly it indicates an ability to conceive of more than one thing at once. With a weave like traveling where, in the female version at least, one has to be able to conceive that two places are the same the ability to make multiple weaves which is directly tied to strength is obviously going to affect how big you can conceive that sameness to be. The ability to conceive representing your ability to make multiple weaves also explains the difficulty a channeler experiences to make ANY weave work easily when she has already learned another. The description of how hard it is to weave multiple weaves neatly explains why a channeler using a replacement weave is in a way thinking of two weaves at once and therefore has difficulty regardless of the fact that she is capable of producing the proper effect. It may even be that the excess power being used is the ammount needed for the phantom weave. But I'm digressing. This discussion has been the use of one persons Talent to disprove what the text supports. Both the persons you have used to demonstrate weak Talent as well as strong Talent are unsubstatiated and in the case of Aviendha blatantly contrary to her own point of view which states her very first Gateway did not require that much of her strength. Without proof Flinn could have the same issue or just be tired. Reanne could be benefitting from the repetitive nature of her Gateway to that location i.e. she was able to "conceive"of a larger gateway in that instance because she already knew the base information from repetively going to the same place from the same place. It's likely Traveling somewhere else or from somewhere else would reduce her down to her proper size. Androl is the only channeler we have proof of having a Talent anyone else is conjecture and as you can see from above I can conject plausible reasons for those same "discrepancies" that take into acccount things we know about the one power.
