Kilt material experiences

[billsides]

I am a new member here but have worn kilts for 51 years. I own many and wear one not less than 3 times a week and my experiences differ at times from what I read on this site. Perhaps some posters had little experience before writing so wrote what the salesman said which is not always true!
My kilts range from cheap E-Bay Acrylic Pakistani to mid range off the hook PV, relatively cheap made to measure Scottish made wool also off E-Bay to very expensive made to measure in Edinburgh of both 13 and 16 Oz weights plus a couple of well used wool ones that I was given.
The Pakistani Acrylic ones pill badly but are very comfortable and reasonably sewn. Now shabby, I wear them almost daily around the house or my garage. They clean easily and have already outlasted many pairs of work trousers. Poly-Viscose kilts are dearer and seems look "new" longer. They pill less so can remain reasonable for a fair while if well sewn. Nylon thread stitching in one Scottish made one let go but was easily fixed with cotton threads. PV is far less wind affected, despite both materials being billed as 16 0z fabrics (which I doubt). My worsted wool 13 oz and 16 oz kilts remain as new after 100's of wearings, seem indestructable, immune to cat fur and hold pleats. I find 13 oz 6-8 yd best in summer for dancing, 9 oz wool is cooler but bad in light winds, has poor swing and is easily damaged by kilt pins so is unlikely to last long or be reliable if going traditional while 16oz 8-10 yard wool kilts will swing and look the best. Old Military kilts are great in drizzle or when bush camping but are not as comfortable due to weight mainly but do seem to last for ever.
I am considering buying low cost kilts for comfort during garage and yard work because I am concerned about fire risk with my old acrylic ones but fail to see how the 9 oz fabrics supplied by many American kilt makers could stay down in outdoor conditions if made like a kilt. Most photos I see show twisted pleats and creases far worse than now on my ancient unpressed Pakistani ones which makes me wonder about quality too!
Maybe somebody with significant experience can enlighten me.
