Leather Types ~ Flogger sting vs thud

Many people have asked me how to know the "feel" of different leather types when used in a Flogger.
I am going to do my best to list the most common leathers and their feel (Stingy, Thuddy, Sound)

I will list these as
S (Sting)
T (Thud)
1-5 (the higher the number the more intense the feeling)

The general rule of thumb is:

The thicker the leather the more Thud;
The wider the tails the more Thud;
The softer the leather the more Thud;

So for Optimum Thud > a soft, thick leather (Bison 8-9 oz, or Elk 3-4 oz) with 3/4" wide tails is premium.
and
Optimum Sting >  a thin, stiff leather (oil tan, Bullhide M/F, latigo) with 3/8 " tails.

Cow Suede ~ 2.5 - 3 oz
3/4" wide tails T3
3/8" wide tails S3

Deer ~ 2.5- 3 oz
No matter how wide or thin you cut it, very soft and very noisy. S1 / T3

Bull Hide (Mocassin) 6-8 oz
Very Heavy, medium softness
3/8" Tails / S2
3/4" Tails / T4

Bull Hide 6-8 oz
Very Heavy, very stiff.
3/8" Tails / S4
3/4" Tails / T4

Oil Tan 5-5.5 oz
Very Heavy, very stiff.
3/8" Tails / S4
3/4" Tails / T2

Bison (American Buffalo) (Mocassin) 8-9 oz
Very Heavy, very soft
3/8" Tails / T3
3/4" Tails / T5
