The SGX is the model that was designed for men of your height. You may want to see about ordering one from this website ( I think it still comes with a money back guarantee). That said, your problems with the Helix may be due to a matter of technique also. Read through the WIKI at http://wiki.malegspot.com/index.php?title=Main_Page
It is filled with information to help you.
