I have several of Steve Godshall's iScandi lines. I like them a lot for near surface fishing, they eliminate much of the line surfing in tricky currents and their increased density makes casting a pleasure. Steve's pricing for a custom cut line will surprise you.
Search out or watch for RIO 6/7 AFS (now discontinued) Factory spec @ 400
Or you could get a Guideline 'trim to fit' version.. nice heads ~ precision tunable.
Many heads run 'fat' compared to factory specification. One manufacturer even has plus / minus 5% disclaimer in the fine print. When splitting hairs it's best to weigh each same labeled individual from rack selection or trim a custom cut to exact desired range.
SGS custom heads is a great option.. (good call sixheads)
A lot depends on what you mean by an "intermediate".
These range from "hover" or "neutral" lines (0.5 ips) that sink very slowly indeed & in a decent flow will fish around just in the top few inches of the water, to a fast intermediate (1.5 ips) which equals the old sink 1 ratings.
Add in the dual density, & now triple density, heads & the mix increases. I have been very impressed by the casting/ handling & fishing qualities of the triple density heads & would recommend you try a float/ hover/ intermediate if you want a slow to medium intermediate sink rate in the uncut Powertaper head - you can then trim this to weight, an #8/9 cut to 35 feet will give 400 grains. Or if you want a short head then a #9/10 cut to 31 ft 8 ins will give the same weight - but, as ever there are variations in manufacturing so always start over length & weigh, then trim back in small amounts until you get the right weight
If you want a faster sink rate there is the float/ intermediate/ sink 2 which having a faster tip will get your' fly down faster to start with but the slower mid section & floating butt will stop it going too deep.
If you want an ready to go head the Powertaper Scandi #7/8 float/ intermediate/ sink 1 sits in between the first two in terms of sink rate & comes in at 417 grains & 34.5 feet.
Give Monty Ward with Vision a call, great guy to deal with and they have scandi's in any sink rate you could want. Another option is call the Guideline dealer in Canada, I think there on your side of the continent there good folks to work with.
Leo it's a triple density Scandi, intermediate tip, hover mid section, and floating rear. It swings straighter than a floater. LTS is the brand. They also make a type 3, intermediate, hover that fishes well in higher flows.
