I think i might have to buy a different rest because i don't want to go back to the 4" vanes, My blazer contact the rest all the time. I don't think it is possible not to get vane contact with this rest and blazers so i think i might have to change my rest. I was thinking of going with a drop away anyway so i guess this might be a good time.[8D]
Thanks for all you help.

I had the same rest and i kept having similar problems especially with the blazers it doesnt seem as though you should get contact but for some reason i was having same problems with ripping fletchings. If you think about the hostage its a good idea the only problem is the whiskers are to short and sometimes the vains come off of them so hard it causes you to get friction marks down the length of the 4" veins. Which has to cause issues with arrow flight.

I switched to a shakey hunter and have had 0 problems since.

I tried a Hostage w/ blazers also.
There is not enough clearence for the 2 down angled vanes to clear the housing.
Blazers are too tall. The Hostage needs to be 1/8'' bigger or you need to be able to move the support bristles up a hair.

Looks like you might be on to the problem.
