I have climbed both lines and several other "variants" through the area of the rising traverse on Syrinx. That traverse is protectable, just not obviously so. It helps to be a bit creative and with offsets, opposing pieces and long slings. The choice isn't so clear in my mind as to which line is safer. What you might gain in available placements you loose in rock quality. That face beneath the orange scar is highly eroded and full of creaky flakes and fragile rock. Not that that in itself make taking the line through Lute unsafe. There is just a trade off in choosing your line. Wise not to approach Syrinx with the same casualness you might on a well trodden classic found on bomber rock on some other bit of the mount.
