Converting LP
To find the best items to convert your LP into following this link: https://www.fuzzwork.co.uk/lpstore/sell/10000002/1000130/withblueprints then sort by isk/lp so that so that the higher isk/lp items are at the top. The items in green will be the best items to convert.
You will also need to do some research on how often those items sell. There is no point dumping all your LP into hundreds of an item if only a couple sell per day.
