Reviewing Dunlop’s iDapt frames presents an unusual problem: There isn’t a stock version on which to base it. There are three cosmetic choices per head size, three levels of dampening, two lengths and six grip sizes. Based on how we configured our test frames, the Force 98 was our favorite. It had the friendliest feel at contact, and the extended length resulted in serious pop from the baseline and on serves. It’s also quite spin-friendly, which was needed to rein in the power that some testers found unruly. Even though it is assembled with two distinct pieces attached by a bolt, sturdiness was never a concern. “I never would’ve guessed that this frame was constructed any differently from standard racquets,” one tester said. At net, the Force 98 slammed away floaters and overheads with the best of them, but the added length caused some mobility issues. “On quick exchanges, it felt like I was trying to swing the racquet through water,” said a tester. The great thing is that the slow handling and elevated power are not deal-breakers—switch to the standard length and it becomes a faster, more control-oriented frame.
