Advice?

I added a few more rows to my Storm at Sea quilt.  Now it is time to start thinking about quilting and I have NO idea what to do!  I still have quite a bit more to add to this quilt, but I think I want to quilt this section, then add borders. 

I'm playing around with Snail Trail blocks for borders.  What do you think about this?  Too crazy?

I'm pretty sure I will do something a little fancier in all the negative space I plan to put around the edges, but I'm at a loss for how to quilt something as intricate as a Storm at Sea quilt.

Should I just echo all of the seams, like this:

Or should I do an allover pattern, like this:

SOURCE:  Quilt Vine

Or this:

SOURCE:  Quiltscapes on Craftsy

Or possibly this (it's hard to see - there is a large swirl pattern going on):

SOURCE:  Charlotte Modern Quilt Guild

Or this:

Or maybe something with all straight lines like this:

SOURCE:  Quilt Inspiration

Or something fancy, like this:

SOURCE:  The Secret Life of Mrs. Meatloaf

Or this:

SOURCE:  Ramblings from Randi

Gah!  Deciding how to quilt something is probably the hardest part of the whole process!  Any suggestions?

And since I am linking up with WIP Wednesdays today, here is a quick rundown of my other current WIPs:

-I finished stitching my own set of Hello Sun Blocks, just in time to put the February block up!
-I pulled fabric to make a lanyard for my new keys (the old lanyard went bye-bye).
-I have purchased everything I need to make my new skirt.  Next up - trace the pattern!
-I've decided I want to try making chenille bibs, and pulled out my meager supply of flannel, all ready to go.
