Continuing the Quest for a good work-out bar

So.... after concluding my rant against "low sugar" bars that are high in sugar alcohols, I've started trying out different bars.  There's no real scientific method to this--I just try whatever is on sale at the grocery store.

The challenge for me is to find a bar that is ideally made from natural ingredients and that helps me get through my work-out.  Since I'm worried about nutrient intake, anything with nutritive value is the best.  

Here's a few that I've tried over the past week.  The grand idea is that I will eventually get a whole spreadsheet of these going, with rankings.

Raw rev 100 calorie bar Chocolate Coconut Bar.  This tasted OK. It was a bit weird in terms of mouth-feel.  The chocolate-coconut combination was one of my favorite candy combinations as a child, so I had high hopes for this.  But--meh.  The coconut feels a little lackluster because it's not toasted. However, on the plus side, I love the fact that all the ingredients are natural. On the energy factor--I find I need two of these to get through my toughest work-out class. Also (and I didn't realize this would be a problem, but....) the bars are bad on stomach feel--these are tiny so I hardly feel like I've eaten anything. I didn't even know this could be a problem until I tried this bar!

Balance bar.  This brand boasts 40-30-30 nutrition profile (40% carbs 30% fat 30% protein). I tried the dark chocolate peanut and actually liked the taste. It had actual peanuts and a bit of a dark chocolate fudge topping. I also found that I was sustained by the energy from it enough to get me through my class. 

Balance bar.  Dark chocolate crunch--this was pretty good--almost like a dark chocolate bar. I enjoy crunchy foods, so this was satisfying.

Raw Rev 100 Bar.  Spirulina dream. This was very.....green. I could practically taste the chlorophyll. Taste was ok. You already know how I feel about the stomach feel of this line.  But it was very....green. What is spirulina anyway?

Odwalla protein bar--chocolate chip peanut. This bar was very grain based--you could literally taste the oatmeal and the other ingredients (a few small chocolate chips throughout). The ingredients were all natural, which is great. It made me feel like I was having a granola bar rather than some manufactured nutrition/protein bar.
