Can you share some of the particular problems you're seeing with re2c/lemon? Either approach (custom or re2c/lemon) is fine - you should pick the one you feel is the best fit to both your skills and the problem. Nor is this a situation where you necessarily have to commit to one approach and never look back - you may find that as you get more deeply into the problem with one approach you are learning more about the problem which indicates the other approach would have been better. You will most likely find that the code you write (and *certainly* the knowledge you develop) will be useful regardless, even you have to "translate" it from one approach to another.
