Line for Winston BIIMX?

[claret dabbler]

Hi, just wondering if anyone has fished with this rod in a 9ft 4wt. I've tried a few lines on it and the best one seems to be 5wt dt Hardy ( can't remember which one ), it's fine with a 4 for the lochs but I bought it for river fishing on windy days and wondered if anyone had experience of it in this role in particular. Any ideas greatly appreciated.

Cheers,

Davie.
