Ok so last summer, i bought 3 rackets from my neighbor. they were babolat pure drive roddick plus. (these were the cortex version, not the new gt ones.) they were all in pretty good condition but the guy who used them hit very hard and was about 5.0 player. i dont exactly know when he got them but i know that it was more than 3 years ago. i have used these rackets for about 1 1/2 years now and have enjoyed them very much. i am a 4.5 player and use red code and gosen og sheep micro syn gut in the crosses at 57 pounds. also i can feel distinct differences between them. for example on of them feels very flexible in the throat of the racket. and one of the other ones shakes and kind of rattles on off center hits. also, his grip size is a 4 1/2 when my hand is definitely a 4 3/8. i have adapted to this but i still think a smaller grip would do me better. i really like the solid ish feel of the roddick plus and i have not tried the gt version yet. do you think i should switch, and get something newer? the other day i borrowed my friends babolat pure storm ltd and i really liked that. a few rackets i want to demo are the head ig speed 16X19, the other pure storms like the regular pure storm gt and maybe some of the new wilson blx rackets. let me know what you think i should do.... thanks!
