Buckwild, looks good! I also agree with Chitown. Your arsenal looks great with a good amount of separation. If I were to suggest a ball in between the Slash and Desert Heat it would be either the Heat Remake or the Solution PP EX.
If you don't feel like buying another ball right now, you can make a surface adjustment on the Slash and tame it down a bit!
Best of luck,
