ok so if i go with the bullet proof cranks i will have a 39.2 mm chain line

if i get something like the action track cranks on harris cycle my chain line would be around 43.5
same with the alien cranks.

whitch one would you guys go with?
i am thinking bulletproof at 39.2 mm chian line just because it is cheap and not out of stock. and also availabel in 165 mm.
(action cranks are 170)
aliens are out of stock but i can wait if this is the better option

here are the links
