I never fill my spools up "full" ... I always leave about a 1/8" gap between the top most line wraps & the lip/edge of the spool. To me, that's full !!
After I took 20-30 yds off, that's what I would guess I've got is a 1/8" gap from the spooled line to the edge of the spool.
Depending on the reel & line, you can sometimes find the sweet spot when refilling line on your reel. Crank it on with tension, until it's full ... then open the bail. If linsie uncoils & falls off the spool ... pull it off until it stops coming off on its own. If line jumps off the spool, in coils & tangles, you've put the line on twisted and it's just trying to uncoil itself. Always check the line for twists, after the first half dozen turns of the handle ... by dropping your rod down towards the line spool & seeing if the line has more turns than before you started cranking the handle. If it does, flip the line spool over & continue filling the reel.
removing the 30yds of line helped but I didn't have time to practice much more after making that change. When I put the new line on, I unrolled the new line out thru the yard/grass, interleaved the line thru my finges and reeled the new line in. hard to say how much tension I put on the line using this method. I then put the smallest/weighted float I had and made several casts out to help settle the line in so to speak, and then started practicing the "shootin" part. I don't think the line is twisted since I laid the new line out in the yard and reeled it in.
The line would just create a small tangle or uncoil itself around the body of the reel after "shootin". I was using the small weighted float to simiulate having a jig on the end so the hook would not create issues.
If you've done everything right in filling the reel with line, and your loops & birdsnests are coming during your shooting practice or actual dock shooting ... your reel spool may be too small for that brand or pound test of line (esp. if the problem presents itself at the beginning of your shooting). If it happens after a period of time of shooting the jig ... your jig may be spinning (twisting the line) or you may not have enough tension on the line when retrieving. Loose line wraps on your reel spool tend to come off in clumps, and even the limpest line will still have "some" twist to it (nature of the reel spool being sideways to the exiting line) ... and even those few coils will drag the other loose coils off the reel, when the line exits the spool.
One of the reels is a bps crappie max UL reel, and am using Mr. Crappie 4# hi viz, brand new from the store. The other reel is a Quantum Torsion (I think is the model) slightly larger than the crappie max reel in overall size. I can see where the line would get twisted after fishing due to the lack of a swivel and such.
If it happens after a period of time of use .... I usually make a long cast & apply tension to the line (w/my fingers) as I reel it back (to remove loose wraps), then resume my shooting. Another method is to remove everything from the line & drag the empty line behind the boat at idle speed, for a few minutes (to remove twist). I let out approx. the top 1/3 of the reels line capacity, then reel it back in under tension. When practicing, I'll open the bail & drag the empty line around the yard until I've let out that 1/3 line capacity ... then reel it back thru the grass, while applying tension with my finger/thumb. The grass undoes the twists, and my finger tension prevents the loose line wraps.
this is how I put the new line on.
Unless your dock shooting is going to be such that you need to hit a 12" square opening, or less (as in shooting under the back end of a pontoon boat) .... don't practice shooting to hit the object you're aiming at, directly, but try & have your jig hit a foot in front of it & skid into it. In practical use, you will get your jig farther back under a dock if you skip the jig across the water's surface, than if you try & shoot it all the way back "in the air". This is especially true when you have limited distance between the bottom edge of the dock & the water. * And remember * ... the closer the dock is to the water, the darker the shade is underneath it !! The darker the shade, the more likelyhood there's fish hiding under there.
I'm trying to hit certain objects to practice being accurate, but realize I need to be able to skip the bait on the water under the dock since things are a bit different from the driveway to being on the water.. I'm just trying to get proficient with the concepts involved with this style . thanks for the help, keep it coming.
