Purchased the 2.16 and added a little weight to each of the four corners. The resulting paddle is very stable and powerful. My drives and counters are deeper with more pace, and it's given me confidence to be a lot more aggressive serving. It's a pretty noticeable change after playing with a Pikkl Vantage Pro for a couple years, but after a month I'm confident to make this my daily paddle and order a second one as backup. The games I play are pretty competitive, somewhere bw 4.0-5.0 depending on the day, and the extra power of the Ronbus is great.
