content: I've seen a few video reviews of breadboards and people are complaining about 830 point BBs having the upper and lower power rails split into L/R halves, and having to add jumpers......I think its great. It makes it super easy to built different stages on a breadboard. Right now I have a BB model of a variable PSU that uses 2 separate transformer winding's, and it just fits neatly with room to spare.

content: I have mine jumpered about 95% of the time, but on occasion it is nice to be able to separate them to get multiple voltage rails.

content: Split rails are great! I frequently have 3.3V, 5V, and/or 12V in a circuit.I just need to remembernotto use the couple of boards I have thatdon'thave split rails.

content: I like to permanently jumper them. Cut a narrow strip of the doublestick foam right down the center of the back, and peel it off. You have room to solder two wires between the power busses, and it still lies flat. Screw it back to the aluminum plate, or put a piece of packing tape over it so the wires can't stick out.If you really want to get crazy with multiple voltage rails, you could buy extra breadboards and take out the power rails and stack them together. So you have multiple rails top and bottom? Seems like all the good boards have removable power rails.

content: Permanently bridging them seems like a lot of work for no real benefit. Takes about 10 seconds to stick a couple of preformed jumpers across the rails and leave them there as long as you like.

content: QuoteBut you only have to do it once, instead of wasting that 10 seconds every single time you use the breadboard. Or if you just leave them in there, it wastes breadboard space.Let alone the time to find or make those "pre-formed jumpers." (I don't use pre-formed jumpers. Tried them. Trashed them. They waste my time, sorting/storing. And once the connections increase enough, you can't use them anymore, because you've built a mound of criss-crossing connections.)

content: I've always used staples (for paper) as the jumpers as they appear to have a standard "spacing" of 0.5" and are thin enough not to damage the contacts. Plus they're cheap. This means they can be used to connect the power rails to the vertical contacts (handy for logic with lots of things connected directly to VCC/GND) leaving the awkward connections for actual wires - which standard 0.7/1 hookup single core does just fine.Breadboarding is still a pain for anything other than simple circuits, so I tend to build modules with stripboard and turned pin headers.
