Bones Bushings review for Skating bowls & pools

I couldn’t find any info on Bones bushings for skating pools and specifically mixing hardness. Saw a few comments online but was all for street skating. Coming from other sports where I’m always tuning my gear I thought I would just test myself and film it. I hope this helps others! I’m 6’2 85 kg 47 years old, been skating around 40 hours now but surf, kite & foil at high level. Let me know in comments if you’d like any other videos on kit I’ve found useful while learning to skate
