I going to be controversial here.
On a river where you have no space to back I can see the point in a skagit on a single hand.
Trout spey - another gimick by and large designed to sell more rods ( a bit like switch rods that are only really short double handers - they are too heavy to cast single handed all day unless
you are 'The Rock' )
Why don't i see the point in them?
- even if you are very good caster they land like you have thrown a stone into a pool
- when you are casting, you make much more noise and disturbance as opposed to if you were overhead casting - so not really a stealthy approach
So, I'm very limited circumstances i see the point ( small overgrown rivers etc) but past that i struggle.
Plus the cost:
Barrio lines - sub £50
OPST running line £33, Head £56, tips £35
I think i'll stick to my smallstream
