Remember when i asked what gag track not to go for?
Now i ask you. What gag track would you prefer to be organic?
I chose squirt to be organic because i wanted to match throw's non-organic power.
Personally I'd recommend either trap, throw or drop. Only because those are the 3 most powerful gags (you don't gain much benefit with organic sound).
Organic train can kill a set of all 12's.
Organic ship does 198 damage and with even a bike horn (and both gags hitting of course), it can take out a group of 12's.
Organic cake.. Bday cake can take out a level 9 without any help. Wedding cake can take out a group of level 10s (without any needed bonus damage). When lured, can take out a group of 11's. When lured, then with someone else throwing cream pies, you can wipe out level 12's.
Those are just my opinions. It matters more what you want for your organic, ie, help kill or only damage cogs, lure or toonup. It comes down to your preference.
