There is no Turning Point made from 7075, I got this confirmed directly from Kentaro.
Werrd can make cheap 7075 throw, because they use cheaper manufacturer.
7075 is becoming popular in Asia, but just material will not make you great yo-yo.
7075 is still more expensive than 6061, takes a little longer to machine and is generally harder to anodize. At the end of the day, depending on the Yo-Yo, there may be design reasons to make it from 7075, but this is probably not always the case.
7075 is great for Yo-Yos that are used for 5A (hey, 5A May everyone!) or 3A where the Yo-Yo is going to take a beating. 7075 is just tougher and the Yo-Yo is less likely to go out of true after taking a beating.
We made an inexpensive 7075 Yo-Yo (a) because we could and (b) because people were asking us for one - and we like to give you what you want.
