OAA/FM vs OGSF

[hunk]

Thanks for the response, Shannon. It's great to hear from the man himself.

Actually, I was keen to know the differences between LTU and AM.

Regarding the free subs, I appreciate your generosity and the fact that you have such confidence in your products.

I'll certainly go through the product descriptions again. I also need to read about the different types of subs (B, D etc.).
