Constructive criticism here....
That is a narrow, small diameter rod you are wrapping around. Which means a LOT of wrapping to spool up your line.If instead you used a larger, perhaps 3-4" diameter spool to wrap around, its less wrapping. Small diameter often tends to promote a kinky, coiled line that seems to tangle easily.
Wrapping line around something like a water bottle will be MUCH faster. You'll likely loose some fish as you wrap up all 30 feet of that...
I carry line on a larger spool for the above reasons. But I don't fish from that same spool. I remove from the spool, and tie to the end of any available pole. We don't have bamboo here, but a 6-8 foot sapling or branch works fine. It doesn't need to be pretty. It just needs to be long. It works to increase leverage, meaning two feet of hand movement equals 5 or 6 feet of improvised rod tip movement, meaning I can land small fish quicker, faster, with less loss. It also means I can drop bait in 'from above' and then pull it out, again from above, rather than 'casting" and then retrieving by dragging over bottom. This is less snagging, and less lost tackle.
That big line is fine. Lots of uses beside fishing. But best carry a few feet of small diameter mono to end with. Big line scares some fish. Snells are fine, but hopefully not all 20# hard stiff mono on big hooks.
Bobber float, a split shot and then a hook works well. But my best rig is something different. Big sinker on the bottom, with the shelled hook attached to the line so the hook is 6" off bottom. Fish with the pole, and the line taut. You'll feel taptaptap or a pulling pickup really fast, faster than with many bottom rigs. Less loss tackle too. It kills panfish
Remember, Big hooks catch big fish, but usually don't catch small fish. Small hooks catch small fish AND big fish. If you have a limited selection of hooks, its usually better to be a bit too small than a bit too big.
