Jack stands or cribs?

The MG is going to be up in the air for a month or 2, stuff under the car needs love and having it a little higher when working on the engine will make my back hurt less.  I have enough jack stands to support front end, axle and even the jack points but the pile of scrap 2x4s out back has me wondering if some wooden cribs might be a better choice.  Looking at a 12-14" lift.  Tires are falken rt615s so the top level would be flat instead of just 2 cross pieces.  My only issue with the cribs is the car rolling off, but a couple of wood 2x2s just to be safe take care of that.  My only issue with the cribs is the car rolling off, but a couple of wood 2x2s just to be safe take care of that. Any thoughts?

I think the guiding decision here is what you're planning to do with the car. Do either of those methods make it easier/harder to accomplish what you;re trying to accomplish? Are you doing any suspension work? Will the wheels need to be off at any point? Would compressed?sagged suspension members make access to what you're working oon harder or easier?

I don't think there's an automatic right answer here. These are similar tools for different situations.

I have cribbing and jack stands. Sometimes I use both in conjunction depending on what I'm working on

Cribbing on top of HF casters, to me this is more stable than jack stands and I find that instead of the car rolling off the cribbing (or stand), it just rolls away instead. 

I think it will be cribs up front, so I have room under the car to remove the headers and jack stands in back under the axle.  

I have both and I use the cribs if I'm not going to be taking the wheels off.
