Let's put it this way ... the 4Point and the Durand Talea were the two arms I used when when developing my new drive system.
The 4Point has a different presentation than the Talea, and it runs the possibility of revealing flaws elsewhere in your system that could easily drive you nuts.
Feel free to contact me about these or other arms (with the usual "I'm a manufacturer / dealer disclaimer).
Cheers,
Thom @ Galibier Design
