balancing twin DCOEs

I'm getting close to firing up my Lola/Datsun D S/R which has twin 45 DCOEs. I have an old style Uni-Syn (clear tube with little red ball in it) synchronize tool but since I haven't fiddled with twin carbs in 40 years or so, and the gauge is older than that, I thought I'd upgrade.

I have been looking on-line at both the 4 port vacuum dial gauges and the carb stick Manometer style, which I will need for a Honda 4 motorcycle project I am working on as well. Anyone here have a preference between them, and why?

Thanks,

Kip

This is what you want.

BTW, I used an "old style Uny-Syn" to tune a triple Weber setup on a stroked Datsun 240Z 3 liter last week because I didn't have much room between the stacks and inner fender. It runs just fine. ;)
