Summary
Tourna, the American tennis brand from Alpharetta, Georgia, has been manufacturing premium co-poly strings since the late '90s. Compared to its legendary blue overgrip (famously used by Pete Sampras and countless other pros), Tourna's string line has flown mostly under the radar. However, if our playtest results are correct, Big Hitter Silver 7 Tour is not to be overlooked. With its ultra-predictable response on full swings, this co-poly earned one of the best control scores awarded by our playtest program. The outstanding control came in no small part from this string's shaped and grippy profile, which helped our crew bring the ball down very effectively with spin. Even more impressive was the fact that Silver 7 Tour held its tension and stayed playable longer than the majority of co-polys our playtesters have tried. Given how perfectly this string fit into our team’s wheelhouse, it's not surprising that they reported zero downsides. That said, this co-poly is likely too firm and underpowered for beginners or players who prefer softer "starter" polys. However, for the poly veteran who wants a seductively crisp monofilament with surgical targeting on full swings, Big Hitter Silver 7 Tour is as good as it gets. The fact that it is priced under $10 and lasts longer than the average co-poly makes it hard to beat.
