William,
Tow with a CG hook is no big deal. I haven’t seen your glider, but if you have a tail skid there is an easy way to replace it with a wheel.

I have a wheel from these guys on my 19 and it’s excellent. We can talk more about the wheel and towing with a CG hook the next time we are both at the field. Its nothing to worry about.
