yep the old crescendo 175 is used exclusively for basecoating with a .5mm needle. the iwata hpcs i use for misting colors and blending and the iwata hpch is for all my detail work. lots of times though i find myself using the hpch for everything. it's a great brush! if you can only get one, get the hpch. there are usually great deals on them on ebay or amazon. i picked mine up for $130.
