After looking at the videos on you tube I'm going with Bowjax for split limbs on my TRT-UL I took a look first hand at the retention spring dampener and it looks good also. Some are using heat shrink tubing on the spring as it helps keep the rubber dampener from moving. The stirrup dampeners look good but I hate to buy a whole kit just for them as they are not sold separate. I notice that Bowjax makes a kit specific for Ten Points. After seeing it in the store, I thought that it may also work on other bows with the same spacing on split limbs and below the rail.
For the solid limb bows, X-Factor makes a "Limb Factor" that wraps over the limb. I would buy two sets and put one set in front of the cable slide and the other over the limbs. I also have the string X's in stock.
I've tried them and like them. They told me it has to do with the rubber compounds that they use. It's not like anything I've seen before and it does work to some degree.
