1. Bottle/pus combo: Dud bottles are basically unlimited if you have at least one dorf, play on a large map, or play any game that lasts awhile and has dorfs as a trade option (especially where water/rain is present and plentiful). Games with high time limits will have many more dud bottles for the taking as well. Ghols seem to throw bottles farther than satchels (true?), and the bottles take an extra second or so to ignite and explode. That extra throwing distance and trigger time allows the ghol a better chance of fleeing before the bomb goes off. But are the bottles weaker than the satchels?
2. Satchel/pus combo: Satchels are in limited supply unless you're playing on a map that allows for multiple dorfs. They are rarely (never?) just sitting around on stock multiplayer maps waiting to be picked up. If they are, you have to run around to each player's starting point to find the satchels that they dropped at the beginning of the game. And using using satchels will almost always require using up points for a dorf if one wants to load up with satchel/pus bombs at the beginning of a match. Unless satchels are more powerful than a single bottle, I'm not sure if this is ever a better option (verify?). It seems as though ghols can't throw satchels nearly as far as bottles, and satchels instantly ignite, leaving the ghol's poor carcass in its wake.
I like to think of these as instant bombs (satchel/pus) versus slightly time delayed bombs (bottle/pus). You can always immediately make a satchel bomb at the beginning of the game as long as you have a dorf. To make a bottle/pus bomb, you'll have to find some water or throw a couple of bottles and wait for a random dud. That wait for a dud will inevitably eat into your ability to position your army favorably in a quick lmonth or ctf match unless you start out next to or cross a body of water.
So is one combo more powerful than the other? Any other pro's/con's that I'm missing? Bonus annoying question: is a pus/mortar bomb even more powerful than the other bombs?
