I recently picked up a really sweet Ozone wasp V1 with the superb black orange and white graphics. The handles are super soft and I wanted them to be stiffer so this is what I did. I think the pipe is polypropelene and it washes up at my local beaches (how beach pollution just grows year by year) The pipe is stiffer than garden hose and is not as rigid as pvc water piping. Inserted under the handle and then taped, the longer the pipe the stiffer the handle is at the junction (but this may stress the main wing body)
