Nanners, they say that peanut butter (and cashew butter) are quite a bit harder to digest than almond or pecan butter (pecan being the easiest). Personally, I prefer the almond butter just because I can buy it rather than making my own
. Pecan butter has a sweeter taste though, and is fantastic in baked goods.
Rider, here is a brand of blanched almond butter, but it's pretty dang expensive: http://www.digestivewellness.com/itempage-1210-24-32-1677.html . If you have the ambition, you could probably buy some blanched slivered almonds from the bulk bin and process it yourself.
The little skin pieces in the regular might not bother you though, I guess it's just one of those things you have to try and see what happens.
