Viper Astro Tungsten Soft Tip Darts vs Fat Cat Bulletz

Both are 18 g soft tip darts for electronic boards, so the choice comes down to barrel and shaft. The Fat Cat Bulletz use a denser 90% tungsten barrel with a shark fin grip, which most players find more secure and more durable than knurling. The Viper Astro counters with aluminum shafts and a larger accessory kit, including 50 tips and a case. Buy the Bulletz for grip and barrel quality; buy the Astro if you want aluminum shafts and a bigger spares bundle.

  • Choose the Viper Astro if you want aluminum shafts, a TacTech case and a large tip and flight spares kit in one set.
  • Choose the Fat Cat Bulletz if grip and a denser 90% tungsten barrel matter more to you than shaft material.

What reviewers say

Viper Astro Tungsten Soft Tip Darts

Owners of Viper soft tip sets generally like the grip and the included case, and treat them as good value for casual and league play. Common complaints are loosening aluminum shafts and tips that wear out and need replacing.

What people mention
  • GripPraisedPlayers say the grooves and knurling give a secure hold for different finger positions.
  • Barrel weightMixedSome throwers find the barrels light for their taste and want heavier options.
  • ShaftsCriticisedAluminum shafts are reported to loosen and need tightening during play.
  • TipsCriticisedSoft tips wear out with use and are replaced regularly.

Questions and answers

Which has the better grip?
The Fat Cat Bulletz. Its shark fin grip bites more than the Viper Astro's knurled bands, which suits players with dry or loose hands.
Which barrel is more durable?
The Bulletz. At 90% tungsten it is denser and wears more slowly than the Astro's 80% barrel, and denser tungsten lets the barrel stay slim.
Are aluminum or nylon shafts better?
Aluminum shafts like the Astro's stay straight and lock flights in place, but they can bend on bounce-outs. Nylon shafts like the Bulletz's flex and are cheap to replace.
Do both work on electronic dartboards?
Yes. Both are soft tip darts with 2BA Tufflex II tips, made for electronic boards.
Is the Bulletz worth stepping up to?
If grip and barrel quality are your priority, yes. The Astro gives you more spares and aluminum shafts instead.
Are both 18 g?
Yes. Both barrels are 18 g and center balanced, so they throw at a similar weight.
