Sure its easier but again, its more likely to break plus Lite Foundations string class is a bit faster because it starts the search at the very end and not at the very beginning like Gstudios function (thats not really noticeable but worth noting imo).

Another thing is: When he gets used to LF now, he can later adopt it more easily and LFs string class together with the other classes is way more powerful than Gstudios implementations.
