The regular release of Saggitario is a yellow, translucent piece. It has several notches and protrusions. The design is loosely based on the original Sagittario, which features two bow and arrows. This version of Sagittario Energy Ring is greenish blueish colour.
Dark has twelve blades facing clockwise direction and is overall round. These blades are pack together with little space between each. The spikes are not wide enough to provide Smash Attack, while the wheel is interrupted too frequently for good stamina. Defense is probably what this wheel is most capable of due to the thick blades, but the weight is too large for its surface area, resulting in poor defense. AD145 and UW145 should help distribute the weight marginally, though. Therefore, most Beyblades that have this wheel should only be bought for collection.
Wide Defense 145 is a lot like Eternal Defense 145. It has three "wings" that protect the Bey from uppercuts. One diffrence between Wide Defense 145 and Eternal Defense 145 is that Eternal Defense can rotate freely while Wide Defense is fixed, giving the Bey more protection from uppercuts but produce a lot of recoil from low attackers like Lightning L-Drago 100HF. When hit by a low Bey, it could fly dangerously off balance and possibly KO itself. An advantage would be that it stop a lot of self-KO that ED145 produce by getting caught at the "hooks" on each wings. It is outclassed by TR145/BD145(Boost Mode on Hell Kerbecs only)/UW145/SW145/R145/GB145 due to much less recoil.
SD is the smallest Defense tip out of SD, D, and WD. SD provide more stamina than D and WD, but has the least defense due to its size. SD would be a good performance tip for Defense and Balance, but D or WD would be chosen over SD if you want more defense. EWD (Eternal Wide Defense) performance tip is a best Defense type out of those three tip since it has both better stamina and defense.
