I have used Claire Bowman Cake Lace. Yes it is flexible and is not hard to eat. I thought it tasted like paper. Although there is a chocolate flavored one which I have not tried yet. I believe you can add flavor to it, but never tried. You can easily cut the cake with it on it or you can peel it of and it will leave the fondant in tact.
I like it very much and find it very easy to use and make. I never used Sugar Lace but heard horrible things about it.
