up to a couple of weeks ago i played with the old liquid metal radical and used a blend at 52/56, but i recently switched to the new volkl pb10 mid. I was looking for a racket which would give me more depth on my s/h backhand and more pop on my volleys and this racket definitely takes care of that, but something was missing, i didnt feel like i got the full potential out of this racket. then i saw this thread and gave it a try. i first started at 35 lbs and it felt good. i was having some problems with high balls, but then again i have only used this racket for a month. Then i went to 40 lbs and it felt good as well. I guess my conclusion after spending a few weeks with this set up and playing numerous hours on full sets of poly (competition) is that, dont leave the strings in too long otherwise everything starts to wane. After about 6 hours of singles and doubles my strings were dead. So having nice fresh strings strung at low tension definitely works for me and my racket. Maybe it might work just as well on the radical, but i am not looking back. I am going to get another volkl and string it at about 50 and see if there is a difference. I havent played with full poly in a long time due to its stiffness, but maybe this racket is taking some of the punishing effects away from my body. I have a stringer and for me to cut out strings and try something new is not the end of the world, but for somebody else, it can really be costly. It is of my belief that depending on your game, to get the same effect from your racket all the time, you must cut the strings out and replace them on a regular basis. I can definitely tell when my strings are going dead. more often than not i wait a day too long before i cut them out and it costs me in my match play. I like the way loose strings play, but you must take full cuts at the ball and believe in your game and your racket. i cant wait to see how the racket plays at 50 lbs. is it really the string tension, my game play or is it in my mind?????
