Hi Ben!
Some guys use chopped GT140's, some chopped MED #7-8's, mill end DT's and Zpey make a comphead for seatrout dist.
I haven't tried Zpey's line as it seems a bit too long for me.
The gt140 is a great line unchopped, but without the mass in the runningline I have trouble keeping the loop "alive" -> it collapses.
I think the idea with "frontheavy" longbellies (MED and others) originally was to counter the mass of the runningline and prolong the loops "lifetime". When the runningline is replaced with mono shootingline (much lighter) one ends up with the opposite reaction -> the loop ?stalls?
But perhaps a reversible head is worth exploring?
In Salmon distance (15' OH) I'm using a homemade head. Currently it contains bits from at least tree different lines...
The taper is similar to that I proposed for seatrout distance, only longer and heavier. It is ok to spey with, a bit on the light side though and for spey I would put more of the weight in the rear.
In the 15' spey event i'm using a nextcast champ cut back to approx. 72ft. Really good line when there is no or little waves and a good tailwind. When there are waves about I borrow a friends line (
TSD spey by Tellis Katsogiannis) cut back to about 70ft. The TSD is much easier to lift when it's a bit wavy.
