I was having a look at those Ruta Locura poles (good suggestion...) the smaller type is 11.5 mm compared with 8.5mm from TT.
That is a substantial difference, however because of the cost of the CF and the fact that the TT are so cheap and if you buy them with the tent no extra postage (or close enough if...) I would still get the Easton.
They have been sold for many years and many are happy with them, I don't really like them but I do put the tents under a lot of tension, not necessary at all in most situations.
I have noticed that Josh at Ruta Locura has an adjuster (8") but only for the bigger size.
The adjustment is not necessary but helps sometime when you want to pitch high or low.
