Ideal way to replace cables/hoses on full ICR frame?

After sitting on this for almost 4 months, I finally made the jump last weekend. Here is what I did:
1. Unhooked derailleurs and brakes and pulled all 4 cable inners.
2. Disassembled the handlebar, spacer, stem and let it hang by the cables.
3. Took off the IIIPro calipers and pulled cable housing from the frame end.
4. Used the RISK ICR tool to route hydraulic hoses thru handlebar and stem first. Took about half an hour even with the tool. The biggest problem is the small rounded rectangular hole thru which you must pass 4 cables without folding them.
5. Rest of the frame, fork was easy peasy. I must have a chosen a good day - the rear hose passed effortless under the BB right into the chainstay under the caliper. Taking out crankset and BB was another of my fear that didn't realize. The first time I did this it was a massive pain.
6. Kept the shifter housing as it is, to my luck nothing got dislodged (especially the FD pickle). After hydro hoses were routed, I passed the shifter cables and they went thru without any effort. Whew!
7. Had kept the hoses longer than necessary on both ends. I used needle insertion tool (extremely handy, a must have) to insert the needle. It is bit of a circus at the handlebar end but it works.
Also of note, the ICR tool works but with a catch. If you already have shifter cables inserted, then the magnetic guide is hit of miss because it sticks to shifter housing. Your best bet is to push the cable guide as deep as possible towards the outlet and then pull with the magnet or a pin thru the exit port.
If you are setting up ICR for the first time, route the hydraulic hoses first and then route the shifter housing.
