Maybe I misunderstood, however when I spool up reels I use a pencil through the hole in the spool and hold the pencil with my toes. I apply slight pressure to the side of the spool so the line winds up snug. REgardless of the direction of spool loaded or reel loaded there should be no twist introduced while filling the reel.
I never have line twist using slip bobbers, except for one brand of bobber stops. The little red figure 8 looking things introduce line twist when you slide the stop up of down.
Assuming your not introducing line twist while spooling. I'm thinking your problem is either line twist introduced when fighting fish, OR your lure is spinning in the current introducing line twist. Try a swivel near your split shot to see if the line twist stops. The other possibility, is tension. You introduce line twist when reeling in and the tension is too light. When the tension is too light, you don't reel in any line, however the spool spins round and round and round twisting up the line. Personally I tighten up the tension, however if the line is small in diameter and your afraid of breaking off, flip that little lever on teh back of the spinning reel so the reel spins in reverse, then us your hand on the crank as tension, unwinding line as the fish pulls.
