Accelerating the line in the purpose of forming a loop...
So making a loop that doesnt unfurl is not it?
Roll cast setup, accelersting the line slowly to make a D loop beside the caster
All speycasts, accelerating the line to form a D loop, single spey, snakeroll, aerialised snap T etc. All makes a loop either fat (D) or tight (V) in the backcast, all underpowered so they dont unfurl but sets the leader and a portion of the line on the water for an alvor to prevent the line to slip backwards after the forward cast has been made.
Double spey, snap T/C etc makes two underpowered loops prior to the forward cast, but for the same reasons as the other spey casts...
You're welcome to call it weird, even though thats a word usually associated with yourself
When is a loop formed in your definitions?
Cheers
