I recently purchased an ultra rest for my allegiance. After about 50 arrows i noticed that my arrow vanes were starting to wear at the felt around the right side of the arrow rest. After about 20 more the felt actually tore and I had to remove it. I'm shooting gold tips with 4" vanes. I rechecked the setup and the tension string seems to be in the right place so I think the rest is dropping as soon as i release. Has anyone else had this problem? Is there anything I could do to correct the problem?
