Just skimmed through this thread and I hope yo dont mind me offering some advice. I've learned to find things and trade using the galaxy map. I guess I can make about two million an hour using just a pencil and paper. There are only a few types of economies and government types. If you play pencil and paper you'll get to pick routes that are very small and straight forward after a bit of practice and you'll know what to buy and sell if you just keep a few notes. Mine have been on the back of rizzlas and envelopes and I've done fine. Not bragging just saying trading is about as complex as the original Elite, for me at least. So dont dash off to a trade tool.There really is no rush.
I enjoy digging around star systems nobody has logged in any trade system. And the profit question is pretty simple - if you want per unit profit of 1200-1300 CR, you need not bother with anything that's less than 5000 CR. Which rules out some of the economies, reducing the number of systems you have to look at. The in-game star map options are great for that. But I didn't learn to look at these things in a time saving and useful manner in-game, I learned that on the internet and from trading tool threads ;-) Maybe I could have figured that out myself, but what with search engines, you can always save your brain cycles for something more difficult than playing a game.
And either way I will always try all tools I can find, as getting great results makes me feel a lot better about flying the rounds. This isn't about rushing for me, its about reducing total time spent trading, so I don't burn out on it. Trading is ok, so long as you don't have to do it for too long at a time.
Just got through trading my way to the 17 million Viper set up, I accidentally sold when trying to retrieve it from storage, because the mouse moved the selection. (I hate that the mouse is sticky on that keyboard interface and always interferes without requiring a click. all you need to do is bump the mouse or bump the table and your selection is changed for you)
As for the Conda argument: I get that you'd need a pretty special route and fly real fast to even up with the T9's 44 extra tons of cargo. And fitted for trading, its 70 million more than the T9 fitted for trading. So if you look at it as a business, the T9 wins by default.
But... In the Conda, you're not sitting in a bare metal truck, farting your way through space. The Conda is more responsive, I've been told and setting it up for exploration can't be too much more expensive than setting it up for trading. It certainly won't be the kind of expense you'd have setting it up for combat. I'm quite happy if I just trade and explore in the Conda and stick to my Vulture for blowing stuff up.
Trading up to the Conda is 62 round trips in my excel sheet or ~21 hours solid. Doable when spread out over time. And what else can we spend the credits on? A Python? yes, eventually, I'll get a Python again, but I want to go exploring with a Conda first ^^
