In reply to JezH:
I'd be interested in understanding if these really are significantly different to Rockcentrics as mine are getting towards replacement time. However, based on the info out there today I'm not convinced they're a massive improvement...
Both have camming effects - and at first glance the overall shapes are similar so I can't immediately see a big difference there.
Torque nut weights are 54-146g (size 1-4) vs 54-156g (Size 4-9). There are no sizes in the DMM catologue so I've just compared sizes by eye. So there's no striking weight saving per item.
The claim of a covering a 'wide size range' may be fair enough but, since they're pretty much the same shape as Rockcentrics are they actually any better in this respect? I only take 4 rockcentrics on my rack anyway...
The main 'improvements' that I can see are:
Recessed faces to protect the sling (though that's never been a problem with my rockcentrics)
doubled slings to give 2 length options.
I'm beginning to suspect that what we'll have here is another Rock vs Wallnut comparison - both are extremely similar, good bits of kit without an obvious winner.
It'll be interesting to see some reviews and opinions when they eventually appear...
