Good review Dave :hurray:
The 90cm is quite a beast for your first Sigma Bri, especially if you were learning on an 800 tile. Best trying with 300s and 600s first to develop your technique as one thing about the Sigma is that it's only effective if you're using it the right way. A lot of tiles react different so you learn what sort of pressure/height/break it needs. Dunno how the TX compares in that regard.
Interesting that you seem to cut with the "big cut" to the right Dave. It's in the Sigma Unwritten Rule Book to keep the big bit to the left. No idea why, think it's from the previous style diagonal machines where you had a full bed on the left and a smaller bed on the right.
