In regards to the use of the TP: I believe in several interviews with either RJ or BS they state that the TP is very different than the OP by how it impacts the pattern, use of the OP manipulates or uses power within the limits of the pattern while the TP actually destroys or impacts the pattern in a negative way (the example often used is when Ishy Travels in the prologue of tEotW, while traveling with OP works around or through the pattern, the TP in this instance actually burned a hole through the pattern for Ishy to get to his destination). Nothing has been really pointed out in the series that the weaves would be all that different from switching over from OP to TP use but the implications on the pattern are certainly there. There could possibly be some hurdles to overcome but we've only seen Ishy (a man very well versed in using it) and Rand use it breifly (but Rand has a ton of info backlogged on use of OP and during times of struggle tends to have these moments of clarity with the OP, its not too much of a stretch to think he couldve done this with the TP at this point).
