in all games, i could easily have unlimited reach by using other mods (lots of mods for cheating etc). and to have more of a challenge, i could play with vanilla reach :-)
but when i want something in between these extremes, i probably will like this double reach, most of all in the beginning when collecting ore and coal from mining drills by hand, before(!) i could do any research. later, i can use mods like extendo to get a bonus in my power suit (having the challenge of balancing shields, reactors, exos, and reach), and small increases by further research (from this mod) are not needed.
i think, using both (this for 12 in the beginning, and extendo for +4 x N later) gives a nice combination for my next game.
