I use the Swivel for just about everything.

I don't veer too far from Terriers and Reliants.  Once those are unlocked I stick with them.

Here are my stock choices.

Favorite design: Mastodon (specifically the default mount)

Favorite launch vehicle engine(s): Vector

Favorite lander engine(s): Terrier & Aerospike

Most reliable engine: Swivel

Most used engine: Vector (need that for lifting heavy payloads, clusters of them in such a small footprint)

Best early-game engine: Swivel

Best mid-game engine: Wolfhound

Best late-game engine: Nerva

Best small engine(by size): Ant. due to it's low mass, i use it a lot on early probes. It's mass more than makes up for it's poor Isp.

Best medium engine (by size): Mastodon

Best large engine (by size): Mammoth.

Most underrated engine: Dawn Ion Thruster (Unrealistic thrust for an ion)

All time favorite: Wolfhound. All my Duna missions require the wolfhound.

 

Here are my modded playthough choices.
