Zyx Universe. O.24 mv vs .48 mv with low eff spkrs

I have a dilema

My Zyx Universe .24mv cartridge appears to be loosing its suspension characteristics. I believe an arm bearing not moving freely put too much wear on it.

I have 84 db speakers and have to crank at pretty high levels to get my volume up far enough to resolve things.

I know a .24 mv is going to have slightly more resolution and speed but woud I be better going with the .48 and having less stress on the amplification and higher output volumes?
