With all the differently opinions on where you get the power, spin, feel, comfort and control in the string bed, I thought it would be a GREAT idea to have an entire thread dedicated to this highly interesting subject here in the string forum on Tennis Talk. In my view after testing literally 100's of Hybrids for the last 2 years, this is how I see it: MAINS - THE MAIN STRINGS PROVIDE MOST OF THE: FEEL, POWER & SPIN in a string bed. CROSSES - THE CROSS STRINGS PROVIDE MOST OF THE: CONTROL in a string bed. In my view you get a bit more COMFORT from the MAINS, but also a GREAT deal of comfort from the CROSSES. The CROSS strings are perfect at taming and controlling the power of the MAIN strings. The MAIN strings are the MAIN PROVIDER of the overall feel and nerve of the entire string bed and you should ALWAYS ALWAYS place the strings, you want the feel from, in the MAINS.
