Lvl 9 Mutator Arena Practice run with Clappy

Been starting to practice doing the arena with Frag-Trap, and holy crap is it a lot harder than I remember. Not a particularly fast round, definitely not as fast as my other one, but that's pretty much due to bad waves. 7+ Ultimate Badasses wave tends to do that. Definitely thinking about changing some skills around just for this, as Clappy is a bit tricky to run in this. Not due to power, as he can easily clean up anything as you can see, but for more survivability maybe? Any suggestions for this are welcome.
