I have 3D lines up to 2/4/6 and they do a job very well indeed,I still use them all with a 5ft poly and 5ft of tippet to the flee and haven't had any problems at all getting down where I need to.
Thing with graduated density lines is they sink differently to 2D or single density lines and although you may well feel they're not down there, they certainly are!,downside is they can fish round a bit faster due to more of the line being higher in the water.
The 3D lines are much more pleasant to cast than say a DWE line of 550,700 or 850 grain and those lines will get down anywhere in any flow of water.
You seem to have it in your head they won't turn over big flies, well if they'll turn over 2"+ of copper tube, then should turn over anything you will be using!
If you NEED fast,Guideline still do some of the 2D lines on 40lb core in 4/5 and 5/6 for the big Norwegian rivers early season.On paper they should be slower, but as there's a lot more of the line itself that gets deeper they will fish slower and find bottom where say the 2/4/6 won't.
Although I don't have the 3/5/7 I know those who do and its a fearsomely fast line in the 700 grain DWE class but easier to cast!.
You need to be aware these lines are fast and quite heavy, not at all suited to 12/13ft rods in lighter grain casting weights, rather than 15ft 10/11 conventional double handers!,although easier to cast than the old style DT and WF Spey lines they'll still need good technique and handling skills.They drop like a stone and can rake the bottom of pools with bad results if you pick the wrong sink rate and as they sink so quick, if you stand there fiddling with the end rig with the line in the water about you, it will soon find the bottom and every single line shredding stone, rock and boulder about your feet.
Just remember, with sinking lines the only thing worse than a line that dosen't sink quick enough for where you're fishing is one that sinks TOO fast for where you're fishing.
Best of luck,Yorkie.
