Rattan dual wielding is more fun for me personally and complex in a way that is really fun. Kali stick fighting (which i have only learned informally) is interesting because it uses the rattan sticks as a practice weapon that can easily be replaced with something more dangerous (mace, axe, sword, etc.) or anything that you happen to find around you when you need it (pipe, stick, glass bottle, etc.). It builds coordination, control of your off-hand, and allows for a lot of creativity. The rattan sticks are useful instead of a metal stick due to their light weight, grip, and how easily they bounce off of other rattan sticks. (They also have a very satisfying sound.) Lots of the practice drills i've done involve both people using them and executing repeated patterns (occasionally with slight deviations) over and over and over until you fully engrain the response in System 1 and can do it as an immediate reaction to a given stimuli. Lots of things make it more fun than the fencing for me(which i haven't done as much of). The extreme coordination, sensation of slashing rather than stabbing, and the strange moves i've learned to do with them are really fun. The creativity, spontaneity, the flow of body movements and impacts, the mental reactions, psychological warfare on the person opposite you (learning how to terrify people with a look or yell is fun), and entire experience is awesome. The fencing that I've done was more historical in nature rather than modern fencing. It used a rapier and a dagger rather than just a single foil. I don't know if I'd reccomend fencing with a foil. It looks interesting but kind of boring. (I would likely learn it just to know how, but not want to do it often.) Dual-wielding itself is strange. I will have to write more about it a bit later.
