It depends...

If you expect most of your casts to be pretty short, say around 30 feet or so, then you may have difficulty getting many of today's faster rods to properly load with only 10 or 15 feet of line out of the tip of the rod. Many saltwater fishermen will overline a rod in this case to help them make a quicker short cast. By overlining the rod, you may have difficulty making longer casts since the rod may be overloaded when you get 60 feet of line out of the tip.

What fishing conditions do you expect? Will you be on a boat or wading? You can generally expect shorter casts when wade fishing. Does your rod load properly for short casts with the recommended line weight? Would overlining it overload the rod for longer casts? You need to evaluate your fishing situation and experiment with your rod to see how it behaves for you.

I agree with LadyFisher about the monic lines; they seem sticky and this is only made worse if you are fishing from a boat and the line sits in the hot sun. If you are wade fishing, get a "saltwater" line. If you are fishing from a boat, get a "bonefish" line. The bonefish lines are stiffer and behave properly when warmed by the sun on the deck of a boat.
