I was experiencing intermittent drag tension. It would come and go at any level of drag I applied. After reading about line slippage on this thread I checked my reel and sure enough..line is slipping on the spool. I'm still confused on how it can have total slip one minute and then work at half strength the next and then back to full drag all within 20 minutes. In the morning I'll find out if a correct line backing will correct this. Would be nice if it's just a simple fix. Thanks for all the input!
