I use 15# Power Pro on a 1500 series spinning reel, 4-8# leader with an Alberto knot, no issues at all. Skip the leader, and zebra mussels eat you alive. Keep that leader at least 6' long, and if you want, you can leave 1/2" of the tag end of braid, fray it, and its a great shallow water strike indicator.

As with anything, match the gear to the cover.

i fish coral infested lakes also. i use 15 , 20 and 50 lb braid with a long leader and have no issues. i will check my line and retie when i need to.

Stealth and finesse.  Easy line management.  Light tackle.

This fish came on that very combination:
