Yeah it works as a temporary fix but as he mentions it's quite a lot of effort-vs-reward when you get to the stage that your dropping numerous fuel sections before you leave the atmosphere, you'd spend the entire process just trying to land things . I think for the time being when I need something hefty moved I'll use a lift system using one big single core of fuel engines with a probe and surround it by layers of throw-away SRB's because their cheap.
Not a fan of SSTO's really, not as fun to launch and I like to build things excessively large .
