Full disclosure-I have a connection to the company but no financial interest. However, anybody that knows me will tell you that I am a brutally straight shooter one way or the other.
I think the Peanut Butter Crunch bar in terms of taste and what you get out of it is the best on the market.
I use, on an almost daily basis, the Meal Replacement and Recovery Shake with a scoop of Energy & Focus mixed in (aka the Superman shake). Based on my research the Meal Replacement is a great supplement and the Energy & Focus has some kind of magical restoritive powers I don't pretend to understand. I swear that my mental accuity and ability to recollect names and facts is better when I use it. In fact, I keep a tub of it at the office just in case somebody wants to see if I am really worth my exorbident hourly rate. It hasn't failed me yet.
The Altitude Advantage is not as good as Diamox in my opinion but then again it doesn't require a prescription and has no side effects so it is what I now use for 12 to 14ers and it seems to work pretty well for me.
Gels-I was with CDN on that trip and can personally attest that what he said was true and accurate. Those gels kept that hunter going all the way back the truck.
Now having said all that, I still occasionally use Hammers Recoverite for hot weather when I am pushing a lot of fluids just because it is very light, goes down easy and tends to stay there. It also tastes pretty neutral if it comes back up.
I think you will continue to see improvements in the existing WA product line as well as some great new additions. I will keep using and promoting it as long as it keeps working for me.
