I can confirm soundless does not make anything take longer but it makes the game a lot and I mean a lot more harder. This can be a good thing or a bad thing in your opinion. The only time soundless makes things go longer through my experience is in the back nine. I have heard people doing it in the same speed as with 4 people having sound however I have never seen it so I can not confirm If you want to speedrun a back nine without sound, what I have seen so far is " YOU HAVE TO HAVE ORGANIC THROW, AND EVERYONE HAS TO EITHER BE TOONUPLESS OR SOUNDLESS" That is unrealible but it is really fun Another thing you have to have is organic throw to make things go fast. Not just that but to makes it 1000 times easier and in so many cases faster when the other players have organic throw. This is also unreliable since this is a choice. So here is the deal with being soundless, It is super fun, but it is super unreliable once you reach later stages of the game. You have to ensure everyone fits your standards later in the game if you want to make things go as fast as with sound. Because of this you usually want to make multi accounts and have friends when going soundless. People will have different opinions and many of the things I said could be wrong. Soundless Is my second favorite trackless to play in the game to play. I encourage more people to go sound less because it brings a new element to the game which many people have not seen. I almost forgot to say, Max all your gags. You can cheat the system and just go to a certain number and you will be fine if you are too lazy to max. However max lure and drop if you are going to do that so you get max accuracy. For toon up I am fine with just having non maxxed juggling balls.
