I recently realized the lack of expressive anything I have for V4 and just my luck, i13's store goes on sale, but I'm a tad overwhelmed. I'm seeing things like RealBite, RealPucker, Boom Lip System, Expression Studio...

Does Boom Lip System make RealBite and RealPucker unnecessary? Does Expression Studio make them all unnecessary?

I could just get them all and be done with it, but I'd really like to avoid wasting money on any possible overlapping products.

One last thing, I use Perfect V4 Complete- does this make half of i13's Super Real unnecessary, or can they co-exist in the same figure peacefully (I realize it comes with 2 of the 4 products I'm confused over, which is why I decided to ask this in the same post)?
