Csp bellcrank or empi hex bar linkage?

I have been reading some good reviews on the csp bellcrank linkage & was thinking of buying one.
I currently have weber 34ict with a empi hex bar linkage & cb performance offset manifolds on the way. Would the csp bellcrank be a worthy upgrade? They seem more precise and well engineered.

Would love to hear your experiences.

I had a look at both and the CSP bell crank is the better engineered. However, one mod I would be keen on doing is to add a quadrant to the pull side as the pull is not linear and the effort changes as well with the angle. CSP could add that for just a few extra pence thus making it near perfect.

I have gone away from any rod actuation and instead I have created a double pulley. There's no problem then with routing through the engine bay and the action is very direct.

I have a CSP type fitted and it is better (IMO) than the hex bars.

VolksWorld did a test on a few a while back, there was a really nicely engineered one but I can't remember the brand/name.

They are still not great which is why I'm waiting on the pulley system (Sync Link) to become available for cars fitted with heat exchangers.

If you don't care about heat look at this, http://www.thesamba.com/vw/forum/viewtopic.php?t=420589

They look soooo nice

if it's any help at all, I'd go for the "optional" spring when purchasing - the unit is not internally-spring, so does not auto centre-return if , like mine, the carb springs are a little weak. ... oh, and a drop of 3 in 1 on the ball-joints at the throttle arm end work wonders :)
Just replaced my GB with one of these ... ideal

I fitted the csp one a few weeks ago. I have the empi clone webber 34 ict's and found the rods supplied to be on the limit length wise. I used the two longest too. I also can't get full deflection on the carbs. The standard cable is too long, so will need reducing or a new one fitted. Having said all that, it is way better than the hex bar linkage I took off.
