My impressions:

Jefe:
Took the Jefe down Green & Rocky B. Bow is radically better than anything I've ever paddled: skims over anything--rocks, holes, you name it. Stays on surface or returns to it VERY fast. Crazy safe for hairball paddling. Best runs I've ever had down each river. A little squirly at 215, but fine for low volume/technical at my weight. Sweet ride--excels in drops but shakier at my weight ferrying & setting up for drops. Would be a little concerned making "must make" ferries. For many 200+ guys this may be more of a low volume creeker. Rolled easy. comfortable. Small cockpit a little scary.


Gus:
Will take down Green this week. Paddled on mighty Nanty last week: GUS felt ELECTRIC (acceleration, manouverablility) and floated me better than the Jefe. Very fast boat. Can go flying in or out of eddies with a lean & get whiplash carves, wheras Jefe mushes. I like the Gus' snappy feel. Despite its speed, the gus corrects/spins easily. Gus would be more versatitle: bigwater, extended trips, and attainment boating (it's that fast. I had fun running gates in it at the Nanty). Has great reputation, but need to see for myself how it handles tight technical.

Conclusion:  
Need to try the Gus on a hard creek to know for sure, but suspect my size & Gus versatility will lead me in that direction. Would actually like to have Jefe also for a quiver.  But who knows, may paddle the Gus & decide the Jefe was better!

After trying a bunch of different creekboats, its come down to these two, which says a lot about LL creek design.
