Right, finally.

One recent sale, that fulfills the criteria (Owner is not reselling): Nope

Naggen: Open suggestion at 1.15 - http://backpack.tf/vote/id/547b3abab88d88b4658b45c5

Cotton: No recent sales, 1.1 is probably fine (juuust touching a month outdated)

http://www.tf2outpost.com/trade/23834739

http://www.tf2outpost.com/trade/22733325 Sold for GBH Tree (5) + Blizzy Rack (~3.4)

8.4 * 0.9 = 7.56 (rounding to 7.6)

Using 7.45

Only two recent sales, and both bought for keeps, so calling one an outlier would probably be unfair (yes, sale 1 had a B/O of 6, but he was also the unboxer so that's not really representative.)

Let it ride.
