I was wondering. what kind of exponential settings are commonly used for 3D and Pattern. I fly a funny kind of set up in which my 3D throws have 80 percent exponential. and my pattern throws are also set up hot with 60 percent exponential. I use the same rudder throws for both 3D and pattern just with very heavy exponential.

plus i am a thumb and finger flier. does this effect how much expo we like to use?

stick length on your tx can have a major influence of the expo 'feel' as well. I run 38 degrees of aileron at all times and have 40% expo and short sticks on the tx. On elevator I run 60% expo and about 45-50 degrees of throw on high and about 14 degrees on low with 35% expo. About the same, 45-50 high/60% and 12 low/35%
It's going to be a different preference for everyone, but I can tell you that running 3D rates on your rudder at all times is going to make snaps a beotch. You really should set up a low rate. A good rule of thumb is just enough throw to sustain knife edge at about 5/8 throttle - that's usually 10-15 degrees.

Aileron
DR 70, expo 55 pattern
DR 100, expo 70 3D

Elevator
DR 23, expo 36 pattern
DR 35, expo 40 pattern spins and rolling loops (e.g., 2006 DLM)
DR 100, expo 77 3D

Rudder
DR 63, expo 63 pattern
DR 85, expo 66 pattern spins and rolling loops (e.g., 2006 DLM)
DR 100, expo 85 3D

The above settings are what I use on my 40% Extra 300. I fly with thumbs.
