I have 3 Dunlop CX Demos out as part of the free program - the CX 200 18X20 Tour, CX 200, and CX 400 Tour. They arrived on Friday, and were tested today for the first time.
My friend, who currently uses the Head IG Prestige Mid with Wilson NXT 17 strings, tried out the CX 200 Tour, and he liked it. The racquet was 0.2 ounces under spec at 11.5 ounces strung with the new Dunlop Iconic 17 string. He said he would need to add an overgrip and some Gamma head tape to it (but he is looking for something slightly lighter and more forgiving than his Prestige Mid). But otherwise, he was pleased with the CX 200 Tour, particularly on serves. He also said the racquet had good spin for the string pattern. He even liked the Dunlop Iconic string, and he is a die-hard NXT guy.
I tried out the regular CX200 and CX400 Tour. My CX200 was on spec at 11.4 ounces strung. My CX400 Tour was 0.2 ounces under spec at 11.0 ounces. Both are good racquets, but I ended up liking the CX400 Tour more as it was more lively and had more power on serve. I would like to try a CX400 Tour that is on spec. Both racquets are also comfortable, and the CX400 Tour doesn't feel as stiff as the older 400s from years ago. For reference, I use the Head Liquidmetal Instinct with Head Velocity 16. I think the Dunlop Iconic string plays like Head Velocity.
Hope to try these racquets out 1 more time this week before I have to send them back on Friday.
