Pros:
You can hang upsidedown and/or ride a roller coaster.
Cons:
You might have a harder time drawing in a stressful situation and it will slow you down a little no matter what.
------------------------------------
I think after you carry for awhile you will no longer want a thumbreak, but maybe that is just me. I have never used one, but then again I only have the really cheap IWB holsters. You do have to be careful with no thumbreak though. The otherday I stuck my holstered gun between my seat and the center console and when I grabbed it the holster was stuck there and came off and I was left holding a loaded gun in my hand. Its not a huge deal.. but you just have to be careful (which I hope is implied with carrying a gun anyhow).
