I have an old TI wand that's been sitting in my garage unused for about 8 years now. The wands about 12 years old. It needs new spray tips. The six tips that are in it 8001. I've read here on tmf about running 02s on the inside and 01s on the outside. I'm kinda confused on whether to replace all with 01 or if there is a better combination? I run a prochem apex at 500 psi. I do a lot of residential and empties. Any suggestions on what tips would be good?
