Back bouncing

[Team goldfish]

Do cannon ball's work better than bank sinker's ?

[Dr.Black-tail]

For me they do

[Artwo]

Absolutely................

Ive never noticed a difference as long as you keep it ticking the bottom,Pick it up and put it down.

I like Bank sinkers because they don't roll like cannon balls.

[Jhmtfly]

I use cannon balls.. But that is because I keep buying it cheap at garage sales lol

[Grantspastor]

I can't see how it would make much difference. That being said I really haven't tried cannon ball type sinkers

I have done a lot of back-bouncing

I think you go with what you got but a tear drop is what I like to use it feels better to me in the water.

Cannon ball gives the most mass for the least amount of surface area.

Surface area is what the water pushes against when fishing in current... profile. Kind of like 40 pound mono vs 40# braid, though not quite that pronounced a difference.

Cannonball sinks faster and allows you to use the least amount of lead on the shortest leash possible given otherwise identical fishing conditions.

Even though a sphere has the smallest surface area to volume ratio, when moving through a fluid body (air or water) it also has a relativly high amount of induced hydrodynamic drag. A more streamlined shape (like a bank sinker) can have a coefficient of drag as much as ten times less than a sphere. When plunking, bank sinkers do cast noticably further and sink noticably faster than similar weight cannonballs, and the much smaller drag coefficient is why.

They also might be a better choice for back bouncing for the same reason, but I doubt there is much of a difference in that application. I use them for back bouncing mostly because that's mostly what I like for plunking and as such then I don't have to own two different types of lead molds.

Come on guys, drag, really? If there's any advantage to a cannon ball I would think it has the least likelihood of getting caught in a crack/branch/whatever. Has a large frontal area and nice rounded surfaces to roll off of those potential snag points.

If you're going to go on the drag thing there's "frontal area" and then the volume of the "skin". I'm trying to remember back to laminar flow (which I presume it is) in fluid dynamics and...and..oh just forgetaboutit!!!

Does anyone remember the "bouncing Betty"? It was developed to address this issue. It was a large "golf ball size" rubber ball that would allow you to drift safely with little current.

This is geting nerdy so I can't resist

Your picture is off due to current hitting the side of the bank sinker, not the end like you show in the picture

[Uglygreen]

I agree. All I said was that bank singers cast further and sink faster than cannonballs when plunking. In those cases the sinker is oriented as in the picture. I doubt it would make a noticeable difference in back-bouncing.

Thanks guys was just wondering if there was a prefrance . I use both only because I bought 1 1/2 to 41/2 cannon ball mold . 21/2 was the magic # tonite . Hard to beat fresh springer I'm stuffed .

Bingo......

The cannon ball won't hang up in some places that bank sinkers will.

In really snaggy fast water I'll sometimes use a "spider type" or custom bottom walker. Basically it's a big square piece of lead with all the edges slightly curled up so it slides over the rocks. The eye is placed dead center on top of the lead. But, most the time, another vote for cannonballs.
