I went to hoyts web site and went to the Reflex site and no luck, was just hopping that someone on here might still have one and as far as string material the 452X you mentioned is in my opinion not as good as string as UltraCam and is deffinatly not even close to the XCEL. The 452X is rough as for the other 2 I mentioned are smooth and 452X is not as strong and takes more material to make a finished string causing a loss of speed and adding more noise to the bow. Since I have been using XCEL all the people I have made strings for just love the extra speed the strength and stability and the quietness, only one person thought he still wanted leeches back on the bow string for looks. You need to have someone make you a string from XCEL and you will be a converted also.
