Granite Peak gear?

I'm planning on climbing Granite Peak (Montana) in the beginning of July and I was wondering if anyone here had done it around that time in previous years and what gear you brought. I'm particularly interested in footwear. It looks like a lot of scrambling so I'd like to wear my approach shoes (Hurray for sticky rubber!). But I've also heard there can be a lot of snow/ice. Will I need to kick steps? Do I need crampons? Should I wear my plastics? I'm hoping I can get away with climbing in my approach shoes since I think that'll be faster and more enjoyable. Any advice would be welcome.

Thanks in advance,
Julia
