I dont understand storing any bow braced. I know many people do this with no ill effects but from a physics standpoint it doesnt make sense. Glass is tough stuff but it has its limits. Putting more stress on it than necessary is just, well not necessary. I am a fan of the push pull method as I have to brace an unbrace more bows than the average bear and it is quick, easy, and safe if done correctly. If a recurve has the slightest bit of limb twist from the time it was built (and many do)leaving it braced will exacerbate the problem over time. This gets worse if the bow is subjected to higher temps or if you use a relatively high brace height. You can make a simple push pull device by drilling a couple 1" dowells into a sturdy wall or bench and covering them with a piece of old garden hose so you can brace your bows when you need them quickly and correctly and it may make yours bows last longer.
