Haloo recommendation for a beginner?

I just snagged some things from Amazon while looking for some items for a student and found that I really enjoy a lot of them.

I am looking to place an order from the Haloo site. So far looking at the Sea Shark Pro matte black, and the Sunflare pro. I am running into issues with deciding the material and if the dual tracks are needed? (I am thinking absolutely they are.)

So far I have enjoyed a floating slider from Amazon- Lighting slider or something to that effect? I also have a few sliders. Mot studio wind chime from Amazon, Plane (after reading it appears its a clone as well), and the desperate rabbit. Again, from Amazon.

I enjoy all of them but may return them pending ordering from haloo as it seems redundant with the rabbit snd sea shark.

Struggling with what materials for the Sunflare please help!

P.S. should I snag the Arugia or just wait and get an aura sand?

Sorry for the wall! Thanks for the input/advice!
