Wide Defense (WD), as it's name implies, is the widest of the Defense series of Performance Tips (D, SD, PD). When compared to D, is still contains the gear-like shape and is of course wider with the Sharp tip wider and taller as well. WD also retains the two curved holes D contained but are now thinner, smaller and found on the Sharp tip.
Being wider brings advantages and disadvantages to WD. An advantage is being able to conserve better Stamina than D and SD, due to the more surface area as well as being able to spin at a lower spin-rate that that of D or SD which cannot. A disadvantage however, is that it's worse at regaining balance than D. The wide shape gives WD a harder time to regain it's balance whereas, D does it much easier. This can be terrible, when faced with an Attack-Type. Although, this should not be kept as a worry as it can be an advantage. This should take into consideration when using a Spin Track such as 230 or TH170. D would be a better choice than WD as it would regain balance much easier to help cope with 230. However, while D can regain balance better, it cannot maintain it as well as WD, especially with heights of 170 and above.
At release, WD has found quick use as a Stamina-Type Tip, much better than D and has become top-tier. Despite this however, as many more Performance Tips like AS, EWD, and B:D were released; they have overshadowed WD. EWD has also overshadowed WD due to EWD's bearing to regain balance better and much better Stamina. W²D performs basically the same as WD though but with worse balance but better attack.
Despite all of this, WD is still a great Performance Tip for Stamina despite its many releases. Just like the rest of the D series, WD has use in Stamina. So in all in all, even though WD may not be the best Stamina-Type Tip, it still has use in the metagame and most importantly, is still, a great Stamina/Defense-Type Performance Tip. It is translucent in colour.
WD works wonders with spin stealing beys. Most of them think Earth is a spin steal survivor, but it works only with Earth Eagle 145WD, and not Earth Virgo GB145 BS . It is only because of WD's wobbling ability. However, the 4D Performance Tip, B:D (Bearing Drive), is recommended because of better stamina, defense, and balance.
Some Bladers experience a fast movement from WD, allowing the bey to dodge attackers, attack, or weaken the impact when hit by another bey. With this Performace Tip it moves in a slow movement and doesn't get hit around the stadium as much. It is clear in colour.
