Just aesthetics,they are the exact same for performance![]()
performance is quite the same, the difference is the base.
EK-FC Titan X - Acetal - has copper base
EK-FC Titan X - Acetal+Nickel has nickel base
performant wise they are the same.
thing is, you want the same base in a loop, so if you have copper, you go with the simple acetal, if you have the nickel, you go to the acetal+nickel.
Copper and nickel in the same loop is absolutely fine.
