I'm trying to make a decision on the Dash vs Pivot.
I have a 2019 9m Dash - I fly it on 24m and 22m line sets. It is great to fly, but it just beats the ** out of me on windy days (22-24kts), I cant get the thing in the right area of the window so that I'm confident in jumps. Lighter wind (18kts) however is awesome, and I love the feel of the hybrid C although I barely unhook.
New Dash is cheap. I'm thinking an 11m Dash for <18kts and an 8m Pivot for 22kt+. I've never flown a Pivot, I've been told they are really powerful so you need a size down from your regular kite. I can imagine what they are like due to the shape, seems like the Slingshot Rev 2 which I had for a while. Easy boosting, low power loops and more forgiving in windy conditions.
It kind of depends on what type of riding you like to focus on. I rode Pivots from 2015-18 but this was when they were tuned more as a wave cross-over kite. With its successes in big-air, it has subsequently been tuned to advance this style with a higher aspect ratio etc.
I would call the Dash a more all-rounder/free-style oriented Kite and I don't think this has changed since it's inception.
I don't think you can go wrong with either kite but I think if boosting is your jam then an 11/8m Pivot combo would do the trick. You'll have a familiar/consistent feel in all conditions this way and your riding will benefit. I've read the 2022 Pivot was a standout model and may be a cost effective option.
