First is a NOOB question, and that is what is the difference between 16g, 17g, and 18g? I don't know what the different gauges mean x_x Second is, has anybody played with Tecnifibre Pro Red Code string? I use a k6-1 team, would this be a good string for the racquet? I was thinking I'd string it at maybe 60 lbs, but I don't know too much about stringing so I figure I'd ask here. Any advice / other string recommendations would be much appreciated! Thanks!
