My Buying Guides on Tru Pro Firewire Boost String Review
When I first decided to upgrade my tennis strings, I came across the Tru Pro Firewire Boost strings. After spending some time playing with them, I wanted to share my experience and guide you through important aspects to consider before making your purchase.
Why I Chose Tru Pro Firewire Boost Strings
I was looking for strings that offered a great balance of power and control. The Firewire Boost caught my eye because of its reputation for enhanced durability and tension maintenance. Being someone who plays regularly, I needed strings that could keep up with my style without breaking too quickly.
Material and Construction
The Tru Pro Firewire Boost is made with a proprietary co-polymer material that feels both resilient and responsive. The string’s construction helps to reduce vibration and offers a comfortable feel, which was a big plus for me since I often experience arm fatigue with other strings. If you’re sensitive to shocks or prone to tennis elbow, this might be a good option.
Playability: Power and Control
From my experience, these strings provide an excellent blend of power and control. I noticed that my shots had more pop, but I could still place the ball accurately. This balance is crucial, especially if you prefer an aggressive baseline game but don’t want to sacrifice precision.
Durability and Tension Maintenance
One of my main concerns was how long the strings would last. The Firewire Boost strings held up well over multiple matches without losing too much tension. This means I didn’t have to restring as often, which saved me both time and money. If you’re a frequent player, durability is definitely something to prioritize.
String Gauge and Tension Recommendations
I used a 16-gauge version of the Firewire Boost, which felt just right for my style—offering a nice mix of power and durability. For tension, I stuck to the mid-range recommended by the manufacturer, around 50-55 lbs. Lower tension gave me more power, while higher tension improved control. I suggest experimenting within this range to find what suits your game best.
Price and Value for Money
These strings are reasonably priced compared to other premium options. Considering their durability and performance, I found them to be a great value. If you’re looking for quality strings without breaking the bank, the Firewire Boost is worth considering.
