I have a variety of types of circular and find them all ok. If you have a particular type of straight needle you like I would try getting the same material in a circular to start. I just got my first bamboo and am still getting used to the different feel and it has slightly slowed me down. I haven't totally decided if I like them. They are size 13 so I would really have to try them in a much smaller size to say for sure.
