Playtest: Klip Screamer 17

By: Greg Raven

Klip Screamer is one of Klip’s “Pro Doubles” (hybrid) strings, this one combining natural gut with Klip Scorcher (see the playtest report for Klip Scorcher in the September 2003 issue of Racquet Tech).

Klip Screamer 16

Klip Scorcher is a solid-core multiwrap string designed to bridge the gap between monofilament and multifilament strings. According to Klip, Scorcher’s copolymer monofilament nylon core gives it a crisper feel than the typical multifilament, while the two high-tensile fiber wraps give it livelier playability than nylon monofilaments. The outer layer is a pearlized coating of titanium oxide. According to Klip, combining natural gut with its titanium double-wrap nylon results in a durable yet very playable hybrid.

With Screamer, Klip is targeting players looking for the feel and playability of natural gut at a fraction of the price, along with crisper power. The Scorcher nylon helps increase ball control by reducing ball speed.

Screamer is available in 16 and 17 gauges in natural/white only.

In the lab

We tested the 17-gauge Screamer “both ways” — that is, with the gut in the mains and Scorcher nylon in the crosses, and with the Scorcher nylon in the mains and the gut in the crosses. We recorded a stringbed stiffness of each string combination immediately after installation at 60 pounds in a Wilson Pro Staff 6.1 95 (16 × 18 pattern) on a constant-pull machine, and then retested after 24 hours (no playing).

Our control string, Prince Synthetic Gut Original Gold 16, measured 78 RDC units immediately after stringing and 71 RDC units after 24 hours, representing a 9 percent tension loss. See the table for our measurements of the 17-gauge Klip Screamer we playtested. Screamer added 13.95 grams to the weight of our unstrung frame.

The string was tested for five weeks by 78 USRSA playtesters, with NTRP ratings from 3.5 to 6.0 (39 testers in each of two groups). These are blind tests, with playtesters receiving unmarked strings in unmarked packages. Try best online casino list in Canada! We instructed one team to install the gut in the mains, and the other to install the Scorcher nylon in the mains.

We found that Klip Screamer is nice to string, even though the gut is a bit rough, and the Scorcher nylon is a bit stretchy. The gut also feels dry to the touch, but strings up just fine. However, several of our playtesters reported flaking or peeling of the gut when pulling the crosses (with the Scorcher nylon in the mains).

On the court

The ratings our playtesters gave Klip Screamer are a study in superlatives. Klip Screamer 17, with gut in the mains and Scorcher in the crosses, comes in first overall of the 90 strings we have playtested to date, dethroning none other than Klip’s “Pro Double” (gut mains/poly crosses hybrid) X-Plosive (November 2004 RSI magazine). In achieving this score, it placed first in Touch/Feel and first in Spin Potential (a category in which our playtesters are usually stingy in their praise). It also placed second in Power, second in Control, and second in Comfort. To round things out, it also placed third in Playability, well above average in Holding Tension, and above average in Durability and Resistance to Movement.

Klip Screamer 17 also placed well with Scorcher in the mains and gut in the crosses, coming in third of the 90 strings we’ve playtested to date in Comfort, fifth in Playability, sixth in Power, and sixth in Touch/Feel. It also placed well above average in Control, Spin Potential, and Holding Tension, and above average in Resistance to Movement. These scores are good enough for an overall score well above average.


Conventional wisdom dictates that with a gut hybrid, you put the nylon, poly, or aramid in the mains for durability, and the gut in the crosses for feel. This playtest shows why it can be good to experiment. Klip Screamer 17 with gut in the mains really impressed our playtesters, even more than our previous test of Klip X-Plosive.

The common factor among these four tests is, aside from the manufacturer, the use of natural gut, which hints at why so
