608rs bearings vs 608z

My pro table came with 608z bearings. Im at the point where i need to replace some. I have some 608rs bearings already. Just wondering if im making a mistake using them instead of the metal shielded Z style.

It doesn’t really seem like a huge deal of difference to me.

I think the rs bearing would be better as they have seals in them to keep out dirt, water and slag.

Back in the BMX, Skateboards and RC we took the seals out and used a drop on Remington rim oil. They ran smooth , but you did have to keep them clean.
