So I had been considering for a while now (like a year) taking a gamble and trying out the Eagnas PN-1012 clamps for my Mutual Power Titan 7700. What I really wanted was the 3-tooth clamps over the 5-tooth, but was unsure of the quality or even if they'd fit and didn't want to chance it, as I know returning to Eagnas is non trivial and would come with a 15% restocking fee. Well I met someone at my local club today who had an Eagnas machine and let me borrow his clamps. I tried them out in my MP machine and they fit just fine in terms of sliding freely up and down in the clamp bases. I didn't feel that they were too tight or too loose, but they felt like a pretty good fit. I was disappointed that the Eagnas clamps didn't have springs. My MP clamps do, so that when I let go of them, they fall and are cushioned by the spring, which I think is nice. The Eagnas clamps just fall with a thud. Also, the Eagnas clamps are a tad shorter than the MP clamps which concerns me. I would estimate they are about 1/8 to 1/4 inch shorter. They still fit in the clamp bases, but with a shorter stem, I wonder if that might contribute to more potential for draw back? I tried stringing one racquet and I did feel that there was some drawback, though, admittedly, not necessarily any more than with my MP clamps, I suppose. I must say that the Eagnas clamps just felt heavier and more solid overall than the MP clamps which surprised me. I also felt that they held very very well and with very little clamping effort. I actually marked every string I pulled with a charcoal pencil to monitor slippage, and I didn't notice any slipping at all. With my MP clamps, I do occasionally notice slipping. This would seem to suggest that it's worth it for me to get the Eagnas clamps, but my concern is still the shorter stem. Do you guys feels that that is a big deal? Any advice from those who have more experience with stringing machines than I do, is much appreciated.
