Hi, I am a low intermediate player looking for a head-heavy racket. I am interested with both of these rackets: Voltric 20 DG Voltric 21 DG Slim Is there a review regarding those rackets and if I have to choose only 1, which one is better in terms of raw power?
Don't do it. I didn't know anything about the racquets. so just did some research. The DG means they can be strung at a higher tension than regular racquets (up to 35 lbs in the case of the 20DG). Low intermediate players should get tension between 20 and 24lbs, as you are more likely to mishit shuttles. Can you link me the website you are buying from, so we can see what is available in your region? If the Astrox Nextage is available in your region, that would be my recommendation. But any Astrox 77, 88, 99 model would suit you fine.
20DG are from old series low end Voltric racket. 20DG slim are the latest series which had slimmer shaft. Nothing wrong with the the racket as long you didnt blinded by noob logic, higher tension are better. If im not mistaken following voltric low end from 1DG to 20DG, 20DG are the head heaviest & compact head. It would be somewhat sluggish for its swing weight & compact head wont be to friendly for beginner. 1DG, 5DG, 7DG would be easier to handle if you like sledge hammer racket. Anyway what is ur current racket?
