Thank you all so much for the great advice and feedback!

I've made a few changes based on what you have all told me. I'm going to switch out the thunders for some independents, seeing as the majority of you find them to work well for you. I had originally planned on getting bones bearings but was kind of wavering on what to choose. I'll be switching to bones though now. As for wheels, I'm having a hard time finding a sort of middle ground for the durometer so I still need a bit of advice as far as that goes. I have changed the wheels from bones with an 83durometer to spitfires with a 99durometer. I'll probably be spending the majority of my time at a skatepark with this board, if that helps.

Here are the changed parts
