There is an initial big booster than I'm thinking of scrapping. Four of them, attached to the next stage, which is four small boosters attached to the center rocket body. Two stages there. The rocket body is the third. Higher up on the rocket is another set of four small boosters, and then another set higher up still. These four sets of boosters get me out into orbit, and the center rocket (Which is in three parts, large engine to get into orbit, 50 engine to get into STABLE orbit aimed at the moon, another 50 engine to land/take off.) gets me to where I need to go. It still needs some refinement. I need a BIT more fuel for the final stage, but then I'd have to completely redesign the booster stages, as they just perfectly get me into orbit now, with no room for error.
Oh, I forgot. I have a set of six Sepratrons on the lander stage that are INTENDED to be used in emergencies to get one nice burn, or to possibly get me into orbit off the moon perhaps. Still purely experimental, as I haven't gotten that far yet. I doubt they provide enough thrust to get me any real benefit anywhere but orbit, but I want to find out.
If that's all in your surface-to-orbit, not counting payload (everything from the 50-engines and up), then you're WAY over-complicating it.
Noting that my game is modded (with some nomenclature overhaul done by me, as well as fixing/tweaking the nuclear engines, I have KW Rocketry and mechJeb (yes, I cheat with an autopilot. Sue me. I like my perfectly circular orbits.)):
My basic surface-to-orbit booster is much simpler: Central column, 2m size. Pair of the largest fuel tanks in that category, and then the most powerful engine for that size category. Hex/Oct-radial-mount, 1m size, 2 or 3 of the largest fuel tanks in that size category, with fuel ducts leading to the central column, and the most powerful engine of that category (and some struts, to prevent wobble). About midway through the lower atmosphere/beginning of the mid atmosphere, the radial-mounts drop away, leaving a fully-fueled central column to boost me the rest of the way and make a proper orbit with.
Hasn't really failed me yet. Oh, and dump the seperatrons. They're not good for much.
