A side note, mono is nice for crankbaits and other treble hooked lures. That stretch is a good thing, it keeps fish from pulling hooks out. I use braid for most everything else though with a leader as needed (which isn't all that often)
A tip for spooling: As previously mentioned, mono backing is required on most spinning reels so that the braid won't slip on the spool. This also helps to fill the spool. As most people know, a full spool will cast much better than a not so full spool. Since braid has a much thinner diameter than the same size mono, it takes a lot more to properly fill a spool, essentially costing you money in line. What I like to do is take a 150 yard spool of braid, measure out 75 yards, and reel that on first. Then go ahead and make your line to line connection to some cheap mono backing of your choice (a uni to uni works well here) and continue reeling until the spool is full. Now, pull off all of the line you just reeled on and reel it on again in the reverse direction so that the mono goes on first and presto, a perfectly filled spool. This also leaves you with exactly 75 more yards of braid to fill another reel.
Two more quick tips for spooling: Make sure that the knot connecting braid to backing is on either the very top or very bottom of the spool. This ensures that it won't interfere with line flowing off your spool while casting. Also, it's best to do all of this in an open space such as your yard. Having lots of line on your living room floor ends up in tangles that you will try to undo, but inevitably give up and throw everything in the garbage.
Sorry for the lengthy post. I just don't want anyone to have to go through the trouble that I had starting out. No stretch superlines may seem like a lot of work initially, but the benefits definitely outweigh the negatives in most situations.
