CR2Builder doesn't bloat files. It also uses a very efficient method of opening CR2s without actually loading the morph deltas into memory, so it won't become sluggish when working with large files. The UI may be a bit daunting for first-time users, but it offers a lot of power, including macros and find-and-replace.
