Use 3/8" for labeling your two and three lead shielded twisted wire. It can even do the 5-6 lead servo runs. It also works if you are adding in a power lead. The
1/4" is viable for single leads and pairs of small wires (such as 20+ AWG). It will slide off single lead small wires because it cant shrink enough.
Big stuff is not very useful.
I picked up some really big (30mm) white for doing bundles. You write on it with a fine point sharpie before shrinking.
this is the kind of info i need, any pics?
Bob, did you use the 1/4 for your wiring harness for VPX
