    Best sinking line I have used - 6/11/2014

    I have the 350gr for my 9wt. I tried the 300gr, it cast well but I worried it would get beat-up by wind on a cast with a large un-weighted fly. I use this when I want to fish any further under the surface than a heavy fly and floating line. My use so far has been for Stripers in small channels. It is very easy to cast. If the wind is down, you can cast to the backing. The running line portion of this flyline is a bit noisy through the guides, but it shoots like a dream. The line sinks fast, true to the chart on the website. It has held up to saltwater so far without a problem.

    performs well - 5/31/2014

    I fish for stripers off the rocks and need a line that sinks fast and can be cast in less than ideal conditions. I bought the 350 grain for my 9wt. It casts well and sinks fast. Caught some stripers on my first trip, so it performs the way i need it to. It did cut into my finger as i stripped the fly in. Bought a finger gaurd and would recommend the same for anyone buying this line.

    Excellent lake line - 5/22/2014
    By: from Las Vegas, NV

    I originally bought the 300 gr. version of this line to use on my 8-wt. Access rod in deeper Colorado stillwater, but really put it to the test in a smaller mountain lake in southern Utah. It was absolutely a difference-maker when it came to reaching splake hanging out near 20-25' in depth. A friend had good luck using another brand of intermediate sinking line to catch the cutthroats and tiger trout suspended in the upper and middle depths, but simply couldn't hook into the splake because of how long he would have to sit around waiting for his line to get low. The Hydros 3D Depth Charge on my reel had no trouble getting down quickly and allowing fast retrieves using Clouser minnows and wooly buggers. I did have some issues with tangles, but bear in mind that I was stripping into a lap basket in a float tube. With a little more space, I think the issue goes away. Overall, this line is an excellent casting, deep running winner for lake fishing.

    Charge up your surf fishing - 5/9/2014
    By: from Flagstaff, AZ

    Great product and is this stuff tough! Gets the fly down where you need it fast, just watch out that you don't get your line looped around structure down below, that is when I really discovered how strong it is and had to cut the line free. So feel assured the loop to loop connectors are bomber!

    Has its Uses - 4/30/2014
    By: from Washington, DC
    Top 250 Contributor

    I dislike fishing sinking lines from the start, but I've found this line to be useful when shad fishing for fish that are 20+ feet deep in the river. It has also served me well for slinging out over dredged channels in saltwater looking for fish down below the drop off. I haven't had any issues with it knotting up on me, but I use a stripping basket in the salt and let it coil on the boat deck in the river. It has more memory than a warm water floating line, for sure, but nothing like a mono-core T-series.

    Well shoot... - 3/16/2014
    By: from Reno, NV

    Not sure what to say. It's a great line for about the first ten minutes or so then it just knots up all the time. Every guy in our group that fish's Pyramid with the Hydros has the same issue. Furthermore, what's disconcerting is that the local Orvis store as well as online customer service state they've never heard of the issue...right. According to some of the old timers in the group, the old Hydros line was perfect then Orvis went and mucked it up by releasing a lesser quality yet more expensive Hydros product.

    Excellent Fly Line Performance - 2/26/2014
    By: from Ibaragi, JP

    Although I thought that this sink-line was probably heavy feeling at first, it will very much easy to treat if it gets used to casting. This #8 Line also matches my #7 Access Rod. I have been experienced very good fly fishing as Sinking style.

    Giant Tarpon will break this line. - 11/8/2013
    By: from houston, texas
    Top 500 Contributor

    I fished this line for giant Tarpon in Costa Rica, and it broke on me three times. I finally switched to another line, even though the replacement line was heavier than I needed. To be fair, Orvis replaced the line after I returned. I chatted online with an Orvis fishing expert, and he could not or would not rate the strength of the depth charge line, arguing that the leader will break before the line will. After I informed him of my experience, he expressed surprise, stating that he had only broken one Orvis line, and he was only aware of three other customers who had broken lines. He seemed reassured by this; I was not. The line has performed well in all other respects, but when other companies rate the strength of their big game lines at 60 and 70 pounds, I think Orvis is making a serious mistake by ignoring this issue.
