I had the Chumee as my groveller for nearly year, helium is very durable, I even kitesurfed on it in light winds and didn't get a single pressure ding. It went ok but I wasn't super impressed with it, but it might have something to do with it being slightly too big for me as its super floaty, so maybe go a bit less volume. I got the Lost puddle fish in carbon wrap now and find it much better in terms of all round performance, if you like FW helium have a look at the Rob Machado Seaside, heard some good things about it.
