What parts did you used to use all the time that you don't use anymore?

If your gonna use a vector, just go mammoth, it's better.

 

To be fair i was also thinking upper stage on a 2 stage design, where you'll ignite low enough down you need good low altitude efficiency, but will be spending enough time high the good upper efficiency is desirable.

The aerospike's good for spaceplanes when you haven't unlocked the RAPIER yet - good thrust to weight ratio, same stack size as the ramjets and decent - if not great - ISP.

Moving on to things I no longer use, though... Autostruts and the new fuel feed priority system made me completely abandon the use of both struts and external fuel lines, and the stock fairings made me almost completely abandon fins. Then there's the new aerodynamics making the old ways of building really wide asparagus stacks far less viable, and suddenly KSP rockets actually look like rockets rather than like a scattered heap of junk and steel rods on top of a forest of fuel tanks. Which is awesome! I mean, the Kerbal-y aesthethics of it all are somewhat diluted, but there's still so much disparity between different parts that it hardly matters. The orange tank is comforting in its complete refusal to blend in with anything whatsoever.

The spaced radial decoupler is also pretty pointless these days, but I think that's more due to me learning how to place decouplers for proper separation than due to anything changing in the game. Then again maybe the new aerodynamics helped.

I still use the spaced decoupler occasionally, but mostly with the Twin Boar.  It gives enough clearance for boosters to sit astride the wider-than-usual end of the engine without clipping into it in ugly (and potentially dangerous) ways.

SRBs, they are just so underpowered. I don't remember the last time I used a Mammoth either, I just put down a number of vectors(usually nine, sometimes seven) and move the gimbal down to 20-30%. Vectors are so OP.

Kickback. It used to be my go-to for all boosters but now I use Twin Boars, as you can Asparagus stage them and give them more fuel and throttle them in flight.

Mammoth has the same power and ISP as 4 vectors but weight 1 ton less so technically Mammoth is more efficient than Vector.

Yes, but it has four vectors with limited gimbal while you could put up to nine vectors in the same space

Seperatrons  (likely misspelled...)

I used to have issues with my radial boosters attacking the central stack, but it hasn't been an issue for a long time.  As such, I usually just save on parts by skipping them.
