I loaded my Tica Dolphin up with 300m of 30lb Samurai braid the other day.
One of my kids did the winding after I pre-set the drag to a reasonable tension.
The reel was on a rod of course with the line fed through the guides. I had already wound on about 20m of 12lb mono as padding for under the braid.
In the winding on process I stood about 5 metres away and held the spool of braid sideways so the line came off the side of the spool in the same direction as it would go onto the reel.
Don't use a pencil through the middle of the spool (only do that for baitcast reels)
As my child wound the reel at a steady pace I let the line off the side of the spool and in my other hand I had a soft cloth that the line also passed through.
I squeezed quite hard on the cloth, applying pressure on the braid to maintain tension on until it had all been wound on.
Afterwards, upon inspection the line seemed very neat and snug on the reel with no evidence of twist.
Then I gave my kid a pat on the back and an ice cream..!
