Agree on the shuttle guard. I had 3M clear underneath and the Ride Wrap Shuttle guard did not stay on. Ended up using contact cement to keep it in place. Now it will only come off when I remove the 3M clear underneath the shuttle guard.
Have wrapped a few bikes now and have only used 3M clear and then custom cut it to fit. But lets be honest, I will never get the 3M clear to fit as well as a custom Ride Wrap. the gaps between pieces of tape are huge. I think for my next bike I will use Ride Wrap. It will save me lots of time and will look much better.
Lastly, I use a fair bit of 3M Mastic 2228 tape for frame protection in high wear areas or in areas that get impacted in a crash. Part of the down tube near the BB, on the driveside chainstay to complement the factory chainstay protector, and on the seat and chainstays near the rear axle. I find this helps protect my bike from the lack of riding skill and reliance on crashing.
