Warrior [Dark Knight] What Spear should I use?

First draft, this will just include some maths and TL;DR. I'll give longer explanations later.

Weapons in question:
Fishing Pole - Fast(5) speed, (3) with booster. I will henceforth refer to this as "Pole".
Sky Skis - Normal(6) speed, (4) with booster. I will henceforth refer to this as "Skis".
Dragon Faltizan - Slow(7) speed, (5) with booster. I will henceforth refer to this as "Dragon".

Max clean attack
Pole: 72
Skis: 99
Dragon: 112
Max perfected attack
Pole: 107
Skis: 134
Dragon: 147
Multiplier given to COMPARED spear
Pole: 28
Skis: 31
Dragon: 33
Formula
[Multiplier of Spear A] ([Weapon ATT of Spear B] + x) = [Multiplier of Spear B] ([Weapon ATT of Spear A] + x),
where x = the additional weapon attack from potions or equipment required for the DPS of Spear A and Spear B to equalize. Any number greater than x results in Spear B yielding higher DPS; any number lower than x results in Spear A yielding higher DPS.
In my opinion, a reasonable amount of weapon attack to get from gear is around 25~35 end game, depending on if we get MoNs or not.
From potions, you can get +100 attack from Onyx Apples, and perhaps eventually +120 attack from Demon Elixirs (they also come from CWKPQ along with the MoN).
Ergo, a reasonable total increase of weapon attack end game is somewhere between 125~155.

Spoiler: Pole vs Dragon

Clean
33 (72 + x) = 28 (112 + x)
(33 * 72) + 33x = (28 * 112) + 28x
5x = (28 * 112) - (33 * 72)
x = [(28 * 112) - (33 * 72)] / 5
x = 152

Perfect
33 (107 + x) = 28 (147 + x)
(33 * 107) + 33x = (28 * 147) + 28x
5x = (28 * 147) - (33 * 107)
x = [(28 * 147) - (33 * 107)] / 5
x = 117

Spoiler: Pole vs Skis

Clean
31 (72 + x) = 28 (99 + x)
(31 * 72) + 31x = (28 * 99) + 28x
3x = (28 * 99) - (31 * 72)
x = [(28 * 99) - (31 * 72)] / 3
x = 180

Perfect
31 (107 + x) = 28 (134 + x)
(31 * 107) + 31x = (28 * 134) + 28x
3x = (28 * 134) - (31 * 107)
x = [(28 * 134) - (31 * 107)] / 3
x = 145

Spoiler: Skis vs Dragon

Clean
33 (99 + x) = 31 (112 + x)
(33 * 99) + 33x = (31 * 112) + 31x
2x = (31 * 112) - (33 * 99)
x = [(31 * 112) - (33 * 99)] / 2
x = 102.5

Perfect
33 (134 + x) = 31 (147 + x)
(33 * 134) + 33x = (31 * 147) + 31x
2x = (31 * 147) - (33 * 134)
x = [(31 * 147) - (33 * 134)] / 2
x = 67.5

TL;DR
Basically, Sky Skis will beat Dragon fairly quickly (NOTE: this is not the case with Reverse or Timeless!). The Pole will need to be perfected and you will need to use an apple for it to beat the Dragon, but will not yet beat the Sky Skis. If you have a perfect Pole, godly gear and are appling (gaining a total of 145 or more weapon attack), then the Pole becomes the strongest. If you have Speed Infusion, Sky Skis win hands down.

For right now:
Use the highest attack spear you can find. If you are appling, use Sky Skis.
When you become godly:
Use the highest attack spear you can find. If you are appling, use Fishing Pole.
