Is it a bad thing if I use my ring finger in spread?

[Gizamaluke]

Okay, so on my left hand I use my middle finger and ring finger while on my right hand i use the normal index and middle finger to play by habit

I was wondering if it's a bad thing to use my middle and ring fingers on my left hand instead of the normal index and middle finger, because I know that it is difficult to move your ring finger independently. This concerned me because with the 7 and 8 songs I have gotten to the point where quick reflexes are needed.

So tl;dr should i just keep playing like this or should I start working on using my index and middle fingers instead, or does it even matter?

Thanks
