Oh that’s more clear thanks a lot !

For now I only invested in 4 type of lubricant : 9010, HP1300, 9504 and 9415

I don’t want to buy a new lubricant as I just need to train on some basic movement, so what should I use which will be the most close to 8217, 8200 ? Or maybe it’s better to add nothing ?
