Just drop off the regs with the included kit at your local service guy and good to go.I'm keen as well, looking between these or the Apeks sidemount set, just need bar gauges! I'm sure in two years I can come drop in and do a service course.
And yes, I feel you on the metric gauges but will still be cheaper if you buy some SPG and short hoses and add on like I've done.
Not frickin orange enough though.
