I think you are right on in your concern for the differences.
The C System Max is a low rg high flare solid. Big motor strong early cover ball.
The new LT 48 vintage is a higher rg lower diff motor in a pushier cover.
Around our wet dry house with often carrydown the big motor C system Maxxed looked really great for some of good throwers. The LT 48 looks great but some days lacks the hit at the back with it's smaller motor. (I have it)
The Versa Max in our house was very over under in box and only seemed to work well when dulled for some of our very good bowlers.
Me....I'd stick with the C System Maxxed if it were me If your condition has much of this slop at the back I'd go for a bigger motor.
...Here's some good ones.

LT 48 is great! Need to power through some slop...C system Maxxed is a good one. Soon to drill mine.
