I don't have much experience and went w/ Sonic 100' last year. Read through this thread, I think I will give Slick-Trick a try. They look very similar to my sonic', but I like the solid Ferrule? at the tip..... the sonic' tip is where the blades come together and as stated above they bend on contact. Sonic's worked for me but the Slick-Trick look like an improved version. What should help me decide what wieght to use?
