I just switched to playing the Head Prestige Microgel Midplus. I strung my previous racquets (string my own) using the Babolat Pro Huricane/Excel Hybrid string set which has each string type coming in 20 foot lengths. My question is - doesn't the Head Microgel Prestige Mid+ require 21 foot mains? How can you string the mains with the cross set in the pre-packaged hybrid combo that is only 20 ft. in length? I have not tried it yet simply due to not wanting to waste the string. Anyone string this racquet and have advise on how to complete the mains with 20 ft. lengths? Thx.
