would blazer vanes be a good choice for my better halfs fletching choice, she is shooting 40# now, soon to be maybe 45# here arrows are 26 inch easton epic st 500, 100grain tips and broadheads..will the blazer preform better than regular 4" vanes??

They won't do any better than traditional vanes, but they will be just as good, and save you some weight over the standard bohning vane. They also work great ina Whisker Bisquit rest.

this is a technical question

I second this. have blazers myself and I like them, I would like to try the limb saver vanes myself though

Blazers will also withstand more punishment than regular vanes.

thanks my main concern was I hope they wouldnt do any worse,if they are just as good I would rather have blazers cause on her bow the 4" vanes touch the WB I dont like that, and yes we both use whisker biscuits too..thanks for the help
