I had a Sevy XK1DS for a long time (2004-2012?) and took it down everything from class I to IV, from tiny streams of 100 cfs to a daily flow record setting big water day on the Ark, and it handled everything well.
After it FINALLY wore out, I bought a Solstice "Flare", which is literally just the newest version of the XKxDS series. Sevy got folded into the Solstice Watersports family, but this is basically the same boat with a few small updates, most notably and for the better the addition of Halkey Roberts valves instead of the old Boston valves. The floor has been upgraded into a drop stitch as well.
I got my Flare in 2017 and proceeded to take it down 500+ miles of (mostly) first descents in Vietnam. Same story, it saw everything from tiny streams to huge water, and performed amazingly every step of the way. Moved back to US around the decade flip and have been bashing down all kinds of fun streams here in the states since. It finally took a rock with some La Garita volcanic glass to take it out. But, I got another identical one and am beyond stoked for this year.
I absolutely adore my Flare; it's small, lightweight, and handles much more like a hardshell kayak than more typical larger IK's. Fully loaded it clocks in at 38 lbs, and with everything off, I can hike it fully inflated as far as I want.
10/10, 5/7, four stars, two thumbs up, whatever rating scale you use, for me it maxes out.
