Caro Fall Rates and Trajectory

Following yesterdays report I have been asked a lot of questions on the differing sink rates of the Tict Caro's. Now I must point out that I do not speak or read Japanese so much of my findings are just how I have been interpreting my own experience.

There is a slight difference in fall rate according to the Caro's type, this is to do with the trajectory of slide, coupled with the water resistance.
Lets take things out of the water a minute. If I am standing on the top of a tower and I drop an apple and a brick at the same time; which falls fastest or hits the deck first?
Well really they fall at the same rate and will hit the ground at the same time, but there is more to it.
A brick is a rectangular prism and certainly if I drop the brick with the smallest surface area facing toward the ground, the brick will fall as fast as the apple. However, if I drop the brick with the larger surface area facing the ground, the apple should fall faster. This is because of air resistance acting as a secondary force, to the force of gravity.
If you think about a rain drop and how fast something so small and light falls, its amazing. A raindrop is perfectly formed to counter air resistance and fall according to the force of gravity.

Well lets take thing back to the water and explain a little about these Caro's. Really a similar principle applies except instead of dealing with air resistance, we are dealing with water resistance and by altering the trajectory of the Caro at the point of immersion, the Caro falls through the water at a different speed. 
However, because the density of water is greater than that of air, the fall in Water has a noticeably different effect, in that an object with a greater surface area fill fall at a different trajectory to that of an object with a smaller surface area.

Ok enough of me waffling, lets see these Caro's in action with this very helpful video provided by Tict themselves;


As you can see, altering the distribution of weight and in turn altering the surface area, the L Caro falls slower, but also at a different trajectory  that of the S Caro ( I don't think I am going to get any marks for my scientific explanation here).

In terms of fishing; say I am fishing a small west facing cove and I am standing on the southerly tip and I want to present my lure at a slow rate to the fish holding up on the northerly rock ledge. I would need to cast short of the ledge when using the L type Caro, in order for the Caro to slide away from me and present my lure to the fish in an approaching fashion. With the S type, I can cast pretty tight against the structure, but the fall would present the lure in a faster and more vertical fashion.
However depending on how near or far I cast the L type to the structure, will determine the depth in which the lure is presented against it and of course you would need to do this to suss out what depth the fish are present.
The same applies throughout the body of water really and in the manner which you select and work the Caro's can help you present the lure effectively to your quarry.
This is but one scenario in which my Caro choice might be helpful, but think about the effects of a fast tidal pull and you might select a different type to use and so on.

Well as I said in my previous post, "my thought are not yet sown up" and even in writing this post I am thinking about how this style is to be used and how it can continue to benefit my fishing.
I apologise if some of this info might seem superfluous and unformed and I would welcome discussion on your findings in fishing the Caro.

Tight lines,
