I know this topic is easily answered being a sponsored skater, but in my opinion training on good wheels is elementary.
Skating on brand new wheels is different from skating on used wheels, both mentally and physically. Whilst training on good wheels you can skate faster, and you have more grip. It’s very important that you have enough grip to be able to skate in the best line, (the line you would also use for racing). Basically you will elevate your training to another level. On top of that it’s very important to trust in your equipment to be able to skate aggressively and at a top level. If you doubt the grip of the wheels entering a corner, you won’t be able to give it 100%.
