Fishing line....

[MuskieBait]

Braid is fantastic for sensitivity and long cast property due to the thin diameter vs. line strength. However, it is terrible for abrasion resistance especially against rocks, shells and coral.

As zippy said, always add a fluoro/mono leader if you need abrasion resistance, a few feet of leader will no affect sensitivity at all.

The one downside to braid is when you are casting light rigs in the wind. Braid, since it is so supple, has a tendency to fly off the spool during the cast, leading to wind knots when it is blown off the spool. It is also prone to forming loops when you first engage the reel if you have a habit to rely on your reel to close the bait mechanically (vs. manually).

Keep those things in mind and you should not have an issue.

I was also hesitant to switch my reels to braid, but not, almost all my reels are filled with braid.

For small UL reels, I would say you don't necessarily need braid...but then again, I landed some very hard running saltwater fish on 8lb braid and 2lb fluoro leader recently. I completely trust it now to handle bigger fish if they happened to take your bait on an ultralight rig.
