"Sashimono question" Topic

Hi. I'm building a small force of 28mm Samurai and Ashigaru for skirmish games like Ronin and Daisho and I have a question regarding sashimono since my knowledge of samurai warfare is quite basic. Were sashimono used mainly in bigger battles? Or were they used a lot also in small engagements? Is it more accurate a small force of samurais all with sashimono or without? Or a mix of the two? Since my main opponents will be Ikko-ikki and Shoei Monks, I will probably build an Oda clan force of 1570-1580.
Sorry if the topic was alredy discussed.
Any help will be much appreciated!

Rule of Cool: Sashimono are very cool, helping immensely in identifying the sides, and indeed marking the battle as Sengoku-era Japanese. Lots of sashimono means a great-looking game.

Rule of Practicality: Undoubtedly they must have been awkward, continuously running into door frames, tree branches, a comrade's spear, etc. I suspect that they would have been displayed mostly for pitched battles and not in camp or on long approach marches. For a skirmish game this might mean having sashimono only on unit leaders.

Rule of Honor: Sashimono served to identify which bushi were pushing deep into enemy ranks, climbing up the enemy castle wall, or otherwise distinguishing themselves. Even in a small engagement, if there was a chance that the lord was observing the action and there was time to afix the sashimono, one might suspect that honor-hungry bushi would not want to risk passing up the opportunity to stand out.
