Like YBD already said, there is no special egg loop knot for fluorocarbon leaders. Just make sure to provide plenty of lubricant (i.e. spit, water, beer, etc...). Fluorocarbon lines generate far more friction when tightening knots than regular mono, causing their knot strength to greatly diminish when tightened incorrectly. Do it right and you'll be in good shape.

On a side note, most true Fluorcarbons (especially Seaguar) break right around where they are rated for. Since you are currently using Maxima Ultragreen for leader material, don't expect to get the same tensile strength out of the Fluorocarbon.
