I use the Danielsson Original exclusively on all my TroutSpey rods for year round fishing and the 3W for 12‘6/13‘ rods, up to 13‘7 in 8/9 and occasionally on 9/10.
But the 3W is way too much for any of the TroutSpey rods, at least mine. And I use uplocking reel seats only, because of rod balance.
Take a look at the 2W version.
I never had problems with lack of speed with trouts on. I also use the 2W for salmon and seatrout fishing. It happens occasionally with a fresh run seatrout or salmon, to be in need for lifting the rod high up and back or stepping back while reeling in as fast as possible. If so with trouts, I would prefer to do the same or take line in with a fast grip to the line here or then to keep in contact and have a balanced outfit for the most trouts and weeks between.
It’s right what already has been said here - it’s no drag/break, just resistance to avoid overrun. Palming is necessary (...the joy...).
The Danielsson Original offers the same resistance forwards as backwards. If one hates a reel with a spool turning in line cast for cast, he will love this concept and the Precision ! Not that unimportant, especially in presentation orientated approaches and TroutSpey.
As said by others, I wouldn’t look around. Just make an order. There is no better offer in relation of price and quality and the best after sales service I know for decades.
Time is running... A little bit of work, a little bit married, fishing, hunting... What else?
