Which node do I pic next REDUX

[Dire_Squid]

Understand that I have Kethane, KAS, and Infernal Robotics...

I've got 550 science (well, 600 now), and either I finally get the claws (which is useless to me UNTIL I can figure out orbiting around asteroids, which I can't do, yet) and get either Nuclear Rockets, Advanced MetalWorks (the winch and stack port, the large kethane drill, more building structures, more robotics, the tiny dock for potential rovers, as the regular ones are too big, the quad coupler and the stack separators), Ion Propulsion (dat Xenon), or Large Electrics (giant battery, and giant solar panels)...

... OR should I blow the whole cash wad, and get Very Heavy Rocketry (without them, I CAN theoretically make it to a Jool Encounter, but nothing beyond that, not even an orbit: I've done it once just to see if I could), Advanced Science Tech (the Nosecone and the Gravioli Detector seems to give a lot of science, even on Kerbin, from what I've seen, and that's JUST Kerbin, which could technically get me back all my Science I spent on them, and add more, along the way), or Hypersonic Flight (I can make my Kethane Jet reach up to a little above 20K m, and reach up to speeds, from that elevation, to well over 1100 m/s... but now I want to make it a genuine spaceplane to survive an around the world/semi-off-world flight)?

The gravioli detector whatever thingy is really useful for getting science, but nuclear engines are definitely helpful for longer trips. If you have trouble going interplanetary with your current parts, the nuclear engine would definitely remedy that, and I recommend you hold off on Very Heavy Rocketry until you are more adept at efficiency, perhaps.

Nothing to see here...

Also since I have 600 points, do I spend it on TWO 300-point things, the ONE 300 point nuclear rocket thing, and wait to get more points for the science? What?
