I have found that using my June Taylor Pro
https://www.amazon.com/June-Tailor-2...hape+cut+prois (the one shown on Amazon doesn't have the diagonal degree lines on it. Don't know why, as these are very useful in cutting diamonds)
is as fast if not faster than using the Go for strips and squares. And therefore I prefer to use it in order to eliminate waste (fabric). I know a lot of people use them for strips and I would too, were it not for the June Taylor mentioned. I prefer the Go or Baby for triangles, especially 1/4" square triangles, tumblers, rag quilts, and if I did applique, I'm sure I would be very happy with those.
I realize that I may not get 100% accuracy on my strips and squares sometimes, but most times I do. If it were not for my "lap cutting" with my Baby (see above post), I would regret not going for the Go to begin with, as it will do a lot more. I am sure you will enjoy either one though.
