So i messed with it all of last night practically and i just couldn't get it dialed in correctly. It would shift to the smaller cogs just fine but shifting from smallest to biggest cogs it would jump a gear or two. Finally took it to the lbs and he was able to adjust everything and get it set up properly. Got rid of the chain snag from the video and fixed my shifting. Even though i didn't fix it i came away with knowing more about rear derailleurs and what screws do what exactly. If something like this happens again or theirs some kind of missed shift going on i'll feel more comfortable "trying" to fix it. Thanks for all the tips and suggestions.
