2004 spools

[Nugget]

Is there a good benefit to going to a 2004 RCS spool?. I have found one pretty cheap and wanting to make sure the upgrade is worth the money. It is a little under half so alot more affordable then a brand newy.

Just after sensitive drag that I can fine tune to suit what im doing.I tend to find I cant find that sweet spot sometimes. Being a shallow lip should see some better casting distance but not sure if it would be noticeable. Then the other factor is can bling up the reel a touch.

Also how much line can you actually fit on them? I use 5lb power pro mostly but might be to thick to get a full spool on ?
