The SWK heavyweight are not really heavyweight. They are about 13oz as compared to 16oz for a 'tank'. They also use about 6 - 61/2 yards of material as compared to tanks. Having said that they do make wonderful first (second and third) kilts. There are even some who only buy SWK and are perfectly happy. Sounds like you have your ordering well in hand and have taken the advice offered here, properly.
