Chainsaw in my opinion is far from over under but if that is what he is experiencing, take the polish off, 2k abralon without polish will smooth this ball up

 

if Boom R'ang is hitting soft it probably is burning up, some polish and a performance enhancing weight hole will liven this ball up, my boom is probably one of the strongest pearls Ive thrown, so much so I dont throw it first game, I wait for some carry down and move left and kill it all night when guys struggle with carry down, ive take the surface to 2k no polish and it really smoothed it out, but prefer it at 2k with polish

 

you dont say how either is drilled that could lead to a clue to the experience he is having
