Quoted from delt31:
Premium over pro - prob one of the best examples of why it's worth it. LE up to you if you see the value.
I would argue it's one of the best examples of saving money with a Pro. The game shoots exactly the same, with the exception of the Raptor Pit, which adds some difference. The moving T-Rex head is cool, but after you've seen it 20-30 times, the effect wears off. It's not like it's a physical ball lock.
If you want some of the perks, Mezel is working on a better sculpted, moving head for the Pro. My guess would be $200, tops. You can add spinning helicopter blades for $25.
So you can buy a pro that shoots exactly the same, and if you want to, add $225 to have some cosmetic goodies.
