I just purchased a new t2 and I really love this machine! Compared to my little f2 this thing is a monster! Its nice having tons of power to spare and being able to change up all the settings for just about any conditions! The only thing I was having trouble with was the very trashy areas. I know once I learn the machine better I will be able to deal with these situations better but I was just wondering if the 5in coil would be a good choice to use when dealing with these really trashy sites? Also I keep seeing people posting about a boost when your set at certain disc or sense settings. If someone could explain what this exactly does or means I would greatly appreciate it. Thank you very much.
