the adrena line did get better with use though but when new it seemed very waxy.maybe it was that that made it hard to sink?
the best sinking line i've ever found was called relix horizon(an impulse buy from flea bay!)only cheap but seemed a decent line.
Adrenaline is pants at sinking and is also very stretchy. I did spool up with it on my spare spools for distance fishing, and although superb for fishing at distance when using a leader, its other properties are, well, rubbish.
If you want a good alround line that doesnt break the bank then look no further than Pro Clear. In 16lb it is superb at casting, sinks well, limited stretch and very strong. I use this now for my distance fishing and pure flourocarbon for smaller waters.
