I had an intern here in 2007 and his work-study was done on rolling and green speed. We used triplex mounted weighted rollers, vibe rollers and a Salsco. The results were that they all produced green speeds in the same range (negligible between the 3 units). We have both weighted and vibes and didn't purchase the Salsco because of safety issues around some of our greens. Weighted rollers would need to be on a 3 wheel drive traction unit if you have slopes around greens. But they are relatively maintenance free and my mechanic likes that. The vibe rollers are high maintenance and almost require regular setup (much like a reel) if you are going to use them regularly. There are a few wear items that we have to keep in stock because out type of vibe head isn't immediately distributed in Canada (done thru 3rd party Toro rep). As for sand distribution, I have actually found that they stir up the sand rather than move it into the canopy. We won't use them on sand anymore.
