Protein Bars - Biggest "Bang For Your Buck"???

Hey Guys - I have tried (as many have you) literally dozens and dozens of different protein bars on the market, and I really like using them as a matter of convenience.  I am always on the go with my job - it's pretty hectic. However, too many times to get a good "payload" of protein, you end up taking in a lot of fat and carbs and/or sugars too in a particular bar.  What I would like to know is, has anyone found a good protein bar (taste is NOT important - nutrition is what I am looking for), where you get the MOST Protein, LEAST Net Carbs/sugars, and LEAST fat of other brands, all in the smallest delivery (total calories)?? I have found ones like Pure Protein, where for 190 calories you get 21 grams of protein, 2 net carbs, and 1 gram of sugar. But the fat is quite high.  I would love something along those lines WITHOUT all the extra fat (well, some fat is fine, just not so much??).... Anyone with any ideas - I would really appreciate it.  I have tried the following: Most Atkins bars Snickers Marathon Low Carb Worldwide Pure Protein KETO a few others... Any idea?  Thanks a lot guys, I really appreciate it very much! :) - Mike

I regularly use the ThinkThin bars (four various flavors). 20g Protein, Sugar Free. They're really good.

I also just today found a new product I really liked. It's a vegan snack made of seitan (wheat glutan product). 10g protein, 4g sugar. 74 calories. I tried the Thai Peanut flavor. Seitan is stringy like shredded chicken, but a little chewier. I really enjoyed it. I ate it leisurly at about 15 minutes and it sat really well. I found it at my local natural foods store. Here's the product link

Pure Protien have the two bars...Chocolate and Smores ...that have 20 and 19 grams of protien, 0 Sugars and 0 trnas fat, they are about 170 calories each and they taste ok enough to have as an in between snack. I get them at Wal Mart.

Chocolate coconut atkins are my favorite..although sometimes when I'm in a "carb" mood...i'll eat zone bars.  Scott
