I bought this for a spare when doing the river in my duck. It appears to be very tough but it is very basic and heavy. The blades don't have as much power as the curved blades and the handle joint is a little sloppy. It does have two feather postions. The handle diameter is comfy. I would get it again as a spare but it would not be my first line paddle. Good value as a rental also.
I have used these paddles for over15 years with hardley a problem. I have IKed thousands of miles of class 3-4+ whitewater, many of which were multi-day wilderness trips with large loads. While heavier than most, I have never had one break. I have seen dozens of other paddles break during that same time, from cheapos to carbon fiber spendy paddles.
A little extra weight is worth it to me.
The 90 inch size is too small for standard IK's.
