I read your post elsewhere and I shall repeat that if you are undecided on a Russian (FSU) woman and a Columbian woman then you need to do some more homework first and decide what you want in a lady.
I suggest you start a thread called "Is a Russian Woman for me?" and state what you want in a woman and why you considered looking abroad - you will reap many years of experience and advice in doing so on this board. Include a brief bio and travel/women experience if you want good specific replies.
As regards tours, I have seen much banter and disagreement on RW boards about Tours. Nobody can say who is the best tour company any more than one can say who is the best agency. People can only recount their own experiences or what they read.
Personally, I would not recommend tours but somebody here will follow me with I think X agency is best. I think there are better ways to meet women but only you knows your character and what will work for you. What brought you to consider tours? Why Columbia/Russia and not elsewhere?
If you help us out here with your line of thought, and background info, you will find a wealth of good (and probably differing) advice here.
In case nobody else has said it yet - welcome!
