Never used the fuel cell never used the bladder....

Bta bottle and one on the seat tube.

Start with bottle bta and on seat tube.
Have spares in special needs only for ironman. Tape gels to the top tube so I can simply rip them off and consume as needed while riding.

Not stuffing around trying to rip open gels or get them out of a fuelselage or re fill the bladder while I'm trying to concentrate on riding fast...
