Well, I'm sure this has been done before, but here goes.  What kind of braking do you prefer on a baitcasting reel??  Please pick one, and also pick which you prefer, internal or external adjustment (in other words, 2 votes).  And please tell us why you like what you like.  

To date, I've used all 3 types, magnetic, centrifugal, and the combination of the two (sort of a combination anyway) as my Bass Pro Extreme has the inertia brake, which I believe I like the best out of all of them.  But I'm looking around for some more baitcasting reels and not sure if I just want to limit myself to the BPS brand of reels only.  So in that case I'd have to consider either magnetic only or centrifugal cause I don't know of any other brands that use the intertia brake.

Mag brakes are simple to use and understand.

And you can tell when they are on and off.  

Externally adjustable mag brake.  But I'm not a zealot about it.

My thumb works best for me.

Ask me this three years ago, I would have said magnetic.  Two years ago centrifugal.  And now?  I have no preference.

I've been very pleased with the braking system on the Revo Premier.  It has taken a bit of an adjustment period.

That said, my gold standard is still the Shimano VBS system.

I have only used Centrifugal brakes to date, so I can't comment on the other types. I will say the the VBS system spoils the angler such that you almost don't need a thumb.

An educated thumb works the best for me.
