I think I would definately go for the riskier situation. You know these people so you know how hard they work and if they really can put in enough effort to make the risk go down a bit! Also, what you said is true sometimes it is hard to really make a big profit without the risk. However, I would say it also depends on if you're just supporting yourself or if you have some youngsters that still need financial support. If so I would probably be a little more cautious with the choice!
Good luck!
