Scandi's tend to be a bit longer for a given weight, with a front end tapering to a finer tip. They are intended for light-ish polyleaders, sometimes sinking but generally floating (or you can just use a mono leader for floating work).
Not exactly. The are an excellent sinking heads on the market, like triple density Guidleine, which have triangle taper, the head travels in the water column under higher angle then a dual density lines and unlike Sagit set-up where thick floating belly act as bobber for sink tip ( T-11, T-14), 3D line ( e.g: Floater-Hoever-Inermediate or Int-S2-S4) enters the water column closer to an angler. In case of faster sink rate lines, most of the line drops quickly under water surface, what substantially reduces a speed of the line ( a surface water travels much faster the mid or bottom sections) and eliminates the need for unnecessary mending.
In case of heads like F-I-S2, I-S2-S4, one can of course use a short polyleader, however considering rather fine front taper, 3-7' leader/tippet can be used, specially for oversized flies. Also, oi case of higher wt. heads, 9/10 or higher , the front 8 feet of the head weights ca. 8-9 gr/foot what enables to case pretty large size flies in needed.
Since the rear part of the head is floats higher then mid or front sections, 3D line are quite easy to lift and can be fish longer then traditional dual density lines.
For example GL 3D wt. 9/10 cut from the back to ca. 37' weights 470-485 gr depending on the sink rate.
In low water conditions when fishing top 6-12" of the water column, F-H-I is absolutely brilliant, fishes great, cuts throughout wind beautifully and cast a tight loops.
