The heavier kilts feels better. It actually feels to me like the StillWater kilt is heavier than my handsewn, even the handsewn is 300g heavier. If you have a perfect average body, you might feel the same with a off the rack kilt. A handsewn is made to fit exactley you, not everyone one the world with a 36" waist.

The handsewn actually looks better, tighter, swing better, and more like a solid kilt. You will also have the advantage that it will not fly up so easily (good to keep in mind when going to ceilidhs).

I have these 3 kilts at the moment, and I like them all three. I could do without the casual one, but I love my Royal Stewart because it just is the best kilt I will ever have. The Black Stewart is good when going to a consert, pub, etc. where I don't want to risk my best kilt.
