It's not a matter of getting access to the parts sooner, my whole point is that I think I get access to the entire part selection too soon. 300 science points is really cheap for the range of functionality across these parts. Even if the fuselage technology is the same, the contents and capabilities of each module is still different. Consider that by not unlocking the 160 point node containing the stock science lab, you've already covered over half of the cost of the composites node for only a small fraction of the functionality. If you're going to edit the tree, I suggest not just adding a single node but an entire branch of nodes that starts out with Whipple Shielding containing a few basic core parts and then lead to nodes containing modules with more functionality. Then there's the IACBMs. It doesn't make sense that you get access to the parachute version of the 1.25m IACBM from SDHI SMS before the standard version, and getting access to the 2.5m IACBM before the stock 2.5m docking port is also unbalanced. I have not suggested this either, I also want to keep it realistic. KIS distinguishes between internal access and external access to a container, making it possible to make both pressurized storages that's only available from inside a vessel and unpressurized storages that's only available from outside a vessel. On the topic of pressurized KIS storage, I've considered the idea of a life support mod that has food as a KIS item rather than a normal resource. Food can then be consumed from each internal-accessible KIS storage in the same CLS space. This way we avoid the unrealistic pumping of food, while still allowing resupply runs.
