I just got my HELIX! I was so excited that my hands where shaking.. and I almost dropped the package. My first ride with HELIX felt so good!!! 🙂 I totally prefer HELIX to MGX. It just slides in and out smoother, and it also produces P-waves easier 🙂 mmm.. After doing some school stuff I had another session which took about 2.5hours.. I took it slowly experiencing everything I could with this new toy 😀 Now I need to be aware of not getting too addicted to this!!! especially now because I have lots of "free time".
