The only thing I would add to what others have said is that all manufacturers of the same size/type needle are not the same. If you find you can't use one needle type made by one manufacturer - try the same type/size needle in a different brand. It does make a difference. And it's a personal preference. My personal preference is Roxanne's but that's just me. And your preference may change over time as well. Don't be afraid to continue to try different types/sizes/brands as you go along.
