I was thinking about buying a Sherwood Avid after hearing so many good things about it. My only problem is it is only affordable if I buy it online and I can not find a shop around me to try one on. I was hoping I could give my dimensions and get some advice from somebody who owns this BCD. I am 6ft tall and weigh between 175 and 180. My waist is 31-32 and my chest is 39. I tried on a seaquest QD and Balance and both were medium. Thanks for any input.
