Clown cartridge is good because you have the potential to get more rockets every time you reload. If you have an armor that lets you hold more heavy ammo, then you will have more chances to get more rockets. With tripod, you will reliably always get 3 rockets which is good but the potential of having more than that is one of the reasons why clown cartridge is recommended over tripod. A good explanation I can give is with my two Radegast's Fury. I have an older Radegast's Fury (ORF) rolled with grenade and horseshoes, field scout, and clown cartridge and a new Radegast's Fury (NRF) with tripod, javelin, and tracking. For ORF, with an heavy ammo armor perk and field scout, I will pick up 4 rockets, 2 in the tube, 2 in reserve. For NRF, with an heavy ammo armor perk, I will pick up 4 rockets as well however it will be 3 in the tube and only 1 in reserve. Now, for NRF, 4 rockets is the maximum amount of rockets that I will ever be able to pick up and shoot. The story is different with my ORF. Since I have 2 rockets in reserve, if I reload after every rocket I shoot and the Clown Cartridge perk procs, I can have a maximum of 6 rockets to fire. So let's say you start out like this: Tube - Reserve 2 - 2 You shoot a rocket (1 - 2), reload, and clown cartridge procs, your ammo count will now look like this: 3-1 (Quick note: You can't reload when you are back at (2 - 1) since your standard max rockets in the tube is only 2.) Now let's say you shoot 2 more rockets (1-1), reload, and clown cartridge procs, your ammo count will now look like this: 3-0 That's a max of six rockets that I've just launched at my opponent where otherwise I should have only been able to launch 4. Without field scout, you have a chance to gain 1 additional rocket because you have 3 chances for the perk to proc instead of 2 with the drawback that you have to reload more often. Basically it comes down to if you want more reliability in your life or you feel like gambling. Tripod would be the reliable perk to have since you are guaranteed 3 rockets in the tube. On the other hand, if you like to take chances and be rewarded for it, Clown Cartridge is the perk that you would get. Hope this helps.
