Thanks for the info. I'll check out your suggestions but the line was an inexpensive "private" item from a supplier. I suspect that's the problem. I have a 8 wt. with good Rio line on it and it shoots so well it bangs the reel when it stops. That is the performance I want in the 4 wt. No body thinks a good quality 5 wt. line would be worth a try?? Tom
