I play with a swing big band. When we play in concert settings,in buildings with good acoustics my session k crashes were perfect. Out of doors and in buildings with concrete floors my cymbals were "washing out". I purchased a16 and an 18 raw bell crashes they work perfect in imperfect settings. The cymbals speak quickly and have a very musical overtones with out washing out. In 18 is great for riding when lower pitched horns, like tennor sax or trombone are soloing. The k cymbals stay home now and I play these raw bells on all gigs.
