I learned on a hanging strop and do 99% or my stropping on one of those. I remember being at my friend's barber shop in the mid '80s and he was showing me how he stropped. He used about a third of the 24" strop in short quick round trips.

The old barber who worked for him grabbed a razor and began doing round trips on his 24" dubl duck strop. He used damn near all of the strop and and said to my friend Joe,"Use the length of the strop, you're stroke is too short."

Note the video of Livi with his extra long loom strop. I have a short Livi loom and a TM 4 sided pasted paddle that I use occasionally but I like length. I imagine a person can gain the skill to get a razor as sharp on a standard paddle but if the length is available I will always prefer that. YMMV.
