If the bit is 3 pieces and pressure is applied, its going to break around the tongue and less pressure is going to be placed on the bars.
I don't think that's right, Maureen. There is always the same contact with the bars.
All bits contact the bars pretty much the same way. That, of course assumes that the double joined, or single joined have the same diameter, material, leverage, etc as each other. So identical bits with the only difference being single or double joined should affect the bars in the same way - it is how they affect the tongue and pallet that makes the difference.
Why the double joined bit is less sever then the single is that the pallet is much more sensitive then the tongue and that is what the singe is make to affect while the double affects the tongue.
