Re-suggest, thanks to K1ng for the help!

Sale 1:

https://marketplace.tf/items/377;5;u90

Sold for 115 USD, keys at 1.97, Total is 58.38 keys

Sale 2:

https://backpack.tf/profiles/76561198310901512#!/compare/1518566400/1518652800

https://backpack.tf/profiles/76561198050062763#!/compare/1518566400/1518652800

Sold with CH Boonie + D@D Billycock + Pro KS Degreaser(7.02) for Time Warp Anger

This would end up bulk, so not using.

Boonie also has no god sales.

Taking 58 flat.

K1ng's part:

Another one sold on marketplace for $85 (~43 keys).

So I would go with 43-45 here.
