Extractor socks

Any concern with pre freezing socks and them not fitting tightly in the spool? I worry about channeling, obv tons of people do it so im off base? I usually dont soak, perhaps thats the “trade off”

this sounds good, so just pack fresh buds tight and hard like dried herb? if stuffing a sock and properly bagging before freezing, doesnt seem like much air space for ice crystals to form, is everyone flash freezing with dry ice or liquid nitrogen, or have folks found that a reg -30 deep freeze is acceptable?
