This attack will cause you to move forward, making it useful for covering ground while attacking.
The attack covers a wide area, so it can quickly strike multiple enemies around you.

-	3,500	35	Unleash a powerful slash. Can attack up to 3 times by pressing the PA button after the slash. Charging the attacks will increase the number of hits for each of them.

PP is consumed when first using the Photon Art. Stages 2 and 3 do not have any additional cost.
Each attack stage must be charged individually. Releasing the charge early will use the uncharged version.
Each attack stage has its own Hunter Arts Avenger window. Blocking an attack with Hunter Arts Avenger on Stage 1 does not grant the boost to Stage 2.
When charged, the attack will automatically fire, so you cannot hold a charge for use with Hunter Arts Avenger, Sword Arts Over Charge, nor Sword Arts Charge Avenger.
Using multiple Calibur Streak stages in a row counts for Same Arts Skip Attack.

tl;drType 1Type 2Type 3

Each Customization is good, but they have different applications.

Type 1 makes it easier to use fully charged attacks, but sharply increases PP consumption. Furthermore, if you don't benefit much from the attack speed increase it offers, it also becomes a practical DPS loss.
Type 2 further rewards you for fully charging the entire attack, but offers no benefit if you're in an encounter that doesn't let you do so. Similarly, there is little penalty for taking this version of the attack.
Type 3 allows for better performance against packs of enemies and grants a ranged attack when charged, but makes the attack have much wider ranges in overall damage output.

Charged Stage 3	2.2365%	78.2775	40	4	5	10 hit	0.9s

Attack speed increase results in swings being about 20% faster.
While the damage of each hit is lower, overall DPS, Down Build rate, and Photon Blast build rate is increased.
Due to the speed increase as well as the PP cost increase, the attack uses around 57% more PP/second when compared to normal Calibur Streak if held for extended periods.

Charged Stage 3 - Two boosts	4.2955%	150.3425	40	4	5	10 hit	1.8s

If either Stage 1 or Stage 2 is charged, the bonus to Stage 3 is 10%. If both are charged, the bonuses multiply with each other to result in a final boost of 21%.
Has even higher overall DPS than Type 1 if you can charge both Stage 1 and Stage 2, and may be preferable in some encounters.

Charged Stage 3	35.5%	1242.5	400	40	50	1 hit	1.8s

Swings slightly faster due to the attack animation change. This results in a DPS increase of less than 1% compared to uncrafted.
While the overall damage output is technically higher, actual performance will vary wildly due to the attack being condensed into a single hit making it much more reliant on Critical Hits than before.
The charged attack has a very wide range, travels far, and pierces targets. It can often cover an entire PSE Burst.
