Their name is "EMS Hooptech." http://www.hooptechproducts.com/ The will be able to answer your question. Just remember that both the ITCTS and the Slimline hooping system come in both a regular and large size. The ITCTS system does have a cap back hoop but the slimline uses a 5.5" round hoop to do the back of caps. Whether or not they are interchangable, I do not know for certain. I would think they should be but it's possible they are not which would force you to purchase additional hoops if you were to ever switch from system to another.
