The Arowana, a straight flying putter with flight numbers 3|3|-1|2 will be a more overstable counterpart to the Koi. I personally use it as a throwing putter that can match my straighter mids in distance. It also will make a great putting putter for those that like a more over-stable flight with a medium feeling depth. This particular run is quite stiff, still able to bend in half, but even stiffer of a feel than the recent run of ecoFLEX Koi and Interceptor (this will help push putters be able to use the disc without feeling it bend in their hand). We feel confident that the Arowana will be a great putter for players of all levels and ages. The first run Arowana is available only in our ecoFLEX material right now, and in 3 different color combinations (as seen below).
