I recently picked up a second set of Hipshot Ultralites. I liked them so much on my RW, I wanted to get some for my 62 AVRI. Thought it would be interesting to compare the weights of the Fender Reverse Tuners vs. Hipshot's Ultralites, so I took them to work and weighed them on a postal scale. Here's the tale of the tape: Fenders = 15.6 oz (442 grams) ULs = 7.7 oz (218 grams) So the Ultralites weigh almost exactly half of the Fenders, with a weight savings of 7.9 oz, approx. 1/2 a pound. So is half a pound enough to cure neck dive? In my case, yes. But as always, YMMV.
