Adamo under seat bags/xlab wings

Racking the adamo from the front of the saddle works...but I also have my saddle all the way forward making the nose essentially longer.  If you have your seat all the way back...I could see how that might be a problem.

I've tried the xlab wing.  To me, it's overkill.  I simply use a bento box and my rear jersey pockets.

For training
2 bottles (down tube and between aero bars)
Bento box with a few gels, and maybe a bar
Small saddle bag holds inflator, levers, CO2, mini tool, patch kit.
My middle jersey pocket carries my mini pump, and a ziplock with my phone, id, credit card, insurance card, and cash
Left jersey pocket carries 2 tubes
Right jersey pocket carries more nutrition if needed.  Flask, bars, gatorade powder, etc.

For Racing...oly and under
1 bottle between the bars
Bento box with flat kit

For Racing...HIM and up
2 bottles (same training setup)
Flat kit taped under the seat (extra tube/CO2 in a ziplock that I put in my jersey pocket in T1).
Bento box with a flask
Additional flask if needed goes in my jersey pocket in T1

I've never felt the need in training or racing to carry more than 2 bottles, or more nutrition than my bento box/jersey pockets could hold.

Yeah my seat's pushed pretty far back. I don't see how well it would rack from the nose. I carry the same bottle set up but was thinking for a 70.3 I was going to have salt tabs and nutrition in my bento and trying to think of a suitable option for carrying a spare kit. I'm still skeptical about the wing method, I just don't see the bottles being comfortably placed as opposed to the downtube and bars as I have it now. Thinking of trying to mount a bag that "sags" from the seat so I could rack inbetween the seat and bag (if that makes sense) but don't want to add drag to my setup

For training in 100F and more 2 bottles just don't cut it.

I go on rides 30+ miles with 3 bottles and that is barely enough.

Hence I am thinking to getting an xlab wing with all the stuff, to allow me carrying up to 5 bottles.

In the TX temps I consume about 1 bottle on 10 miles. 

I'm with this poster.  My sweat rate is very high.  For a 30 miler I need 2 bottles minimum.  On a hot day, 3 are needed.  For a HIM, well last year I started the race with 4 bottles: 2 on downtube/post and two on xlab.  Drank all four bottles.  Not sure why it never occurred to me to bring endurolyte tabs or nuun tabs with me and grab 2 more bottles of h20 at the bike turnaround and just drop both into my current bottles.  Seems like that would save me from having to carry an extra 2.5 lbs around the whole first half of the course.  Ah we live, we learn.

Now if I'm riding a solo century, well I either have to plan for some deli rest areas so I can buy some liquids or rock the xlab.
