Animal is going to roll earlier than the FT, due to the particle in the cover. That being said, I think that the FT would be a great replacement for the Animal. Numbers are similar, and the cover on the FT is much more aggressive nowadays than the MegaFang cover on the Animal.
The Look for a medium ball.. maybe, with polish. The Nuts Pearl is a great throw it towards the ditch ball. If you have friction, it's awesome.
The S75 is going to be stronger than the Look. The Look has a higher RG, and lower diff, so it's going to get down the lane better than the Break.
