Salmon fly line dillema

Choosing a spey fly line is prooving more difficult than I imagined and
experts's opinion seem to vary dramatically, contradicting eachother to the
point that the average punter is confused.

On the one end, you have a respected and vastly experienced Scottish casting
instructor stating in his very good website review of speylines that he
favours a traditionnal DT profile for the bulk of his fishing whilst
prefering modified Wf profiles for pure distance....and on the other hand ,
tackle shops and other APGAI instructors who really only promote WF profiles
and when questionned reply that they hate DT lines.



I started with a Rio Windcutter and now wish to move to the next step, now
that I have acquired the basics. The Rio midspey is the logical choice but I
am overall very confused and at a loss when choosing. Trying with the rod is
best but nowhere can one actually try everything and anything.., especially
not a traditionnal DT 10!

My dilemma is that I feel I know need a longer head ( I have reached maximum
distance with my current line and want to do a bit less spaguetti retrieving
before casting again) but also hate -when fishing smallish streams - to be
disabled because the rod does not really load until most of the head is out
of the top ring.

A 70 feet head is probably the maximum I want to go to as really long belly
lines seem to be for the very proficient caster and adapted only to very
large rivers whilst I fish only medium to large rivers.



In summary, I could do with views of real salmon anglers rather than expert
casters, people who have can testify of their practical experience rather
than loose me in theoritical debates.
