Medium Pips

I want to ask about medium pips, specifically the Yinhe Pluto with sponge. A fellow club member who plays inverted both sides told me that he faces difficulty pushing heavy backspin with inverted and wants to try playing pips on backhand. He also plays mini flicks and topspins on his backhand so I thought a medium pips with sponge would be good. He wanted the rubber to be as cheap as possible, so I decided on this. Would like to hear your opinion.
