Ok, my feedback after using both Manic and Duck for the last few days...
Manic seems to be just that, manic. He tries to hit homeruns, and therefore hits some big one, but also strikes out a lot. That's not easy/good to manage if you try to follow them all on a small account, even with small positions. As mentioned, he has added some value with channels delivering charts and such, which is really good information.
Duck's system is more conservative, as he's happy getting out of a trade at 20-30% most times. He has also had some homeruns, but overall the returns are smaller. However, he rarely has a real bomb that hurts you. He posts watchlists each evening for the next day and is also now including an educational write-up (PDF form), I think weekly. The first one was on identifying levels on a chart. Duck seems more laid back and willing to help/teach his followers to be able to do this themselves.
For me, Duck's system is the best for my style and risk level, and I will likely cancel Manic once the month is up.
TLDR: I prefer Duck's system, plays, and risk assessment.
