i'm stationed over seas and getting mason hard mono is hard at times, instead i use 15-20lb Ande mono. it works great, a lot of the flats in the keys, even the sandy ones will have a good amount of grass and seaweed floating through with the tide. even if grass isnt a problem on a flat there is so much lime stone and coral to het hooked up on that a weed guard is a very good idea. simply tie in a "V" shaped weed guard on smaller clousers and crazy charlies, and on the larger flies like larger clousers and deceivers tie in a loop style guard. most of the "blind" bend backs work well on the bones and dont requiure a guard since they are tied with out eyes they get hung up less and seem to glide from grass top to grass top.
