What's your current go-to launcher?

If you're anything like me, you spend a lot of time in the VAB building, tweaking and then testing your launchers. I've had loads of fun experimenting, but I'd like you to share your experiments with me. We all have the same problems and I'm nosy/interested to know how you're solving them.

Screenshots, KVV shots or even just descriptions are fine, but please do say what the launcher is intended for.

Here's my new medium launcher, with a lander attached. It gets to a 150km Kerbin orbit with around 8500m/s delta-V available. I've used it to go to the Mun, but will attempt Duna later:

I use two rocket collections, LOPAC and Munshine.
