In a word, static. Some records are a nightmare to get out of the sleeve and static attracts dust like dog shit attracts flies. It can affect the tracking weight too.
Any fan of records who does not use anti-static sleeves, is no fan of records.
(Static) Affects tracking weight? I'd love to see the science and maths behind that.
I repeat - I do NOT wet clean anything except second-hand records, I use a carbon fibre brush, I use ant-stat sleeves, as I have done for WELL over 30 years, and have no problems at all with static once the record has been out of the sleeve once.
Getting a record out that first time can be quite some struggle given that I touch only the edge and labels of records, but that will be the last time that that record gives me static problems.
