Royal Wulff Bermuda Triangle Taper Intermediate Fly Line
Built for tropical flats and hot-weather fishing, the Bermuda Triangle Taper Intermediate is designed to keep performing when coldwater lines get soft on blistering decks. It features a clear Monocore intermediate for stealth once submerged, paired with a braided monofilament core and a harder outer layer for warmwater stability.
This line is 105 ft total with a 32 ft head (Triangle Taper Salt), front & back welded loops, and TRI-D Line ID for quick identification. The intermediate density sinks at about 1.75 inches per second, ideal for fishing just under the surface and into the upper water column on the flats.

Great for fishing in warm tropical waters. The line stays firm even on hot days and sinks steadily. The clear intermediate helps see the line underwater. Easy to handle and the loops stay secure.
Connor Gill –
Used it on a flat near the shore. It performed well in the heat and didn’t soften like other lines. The sinking rate is consistent and helps keep the bait in the right depth.
Adam Hodges –
Felt more durable than standard intermediate lines. The braided core holds up well in saltwater. The front and back loops are secure and the line is easy to tie.
