The Jefe is extremely forgiving. The transition from the Burn to the Jefe will take a few trips down the river, but it's an easy one.
Think about trying to stay in a really turbulent eddy on the river... a boat with edges like the burn will have the tendency to react more to the "funny" water. Hanging out in tricky eddies is a breeze with the Jefe because of its lack of edges.
One thing I do find in the Jefe is the increased difficulty of ferries. Initial setup is strong in the Jefe...but the Burn and Karnilli transition a little smoother and calculated.
In addition the rounded hull of the Jefe and pronounced bow and stern rocker make the boat extremely maneuverable and boofable! Landings from vertical are also smoother and safer with the Jefe's displacement hull.
I think you're creeking game will increase two fold with the addition of the Jefe to your quiver
