I know what you weigh and I admire your will to get out there and do something about it. If we lived closer Id love to ride with you as Im a gadget geek too (X10, Robotics, RC Planes,...). Im 280lbs (started at 320 in 2010) so Im no shrinking violet either. I have no idea what 'hit training' is. I just ride my bike - rain or shine.

I dont think you see how you come off when responding to other posters. Read back through the thread - its not just me. Its OK to have different opinions but we dont need to attack each others reading ability etc. It makes people defensive believe it or not.

For me the garmin is the best thing ever. If you prefer to tinker, good for you. Just my 2c and nothing personal.
