Absolutely... you need to have offset or helical vanesto steer any broadhead.

You definately need a helical fletching. I used to use a straight fletch (didnt know any better) and I never could get my broadheads to fly right. Also make sure your bow is papertuned. I was having the same problem a few weeks ago with mine hitting low and right. I papertuned again (something must have moved) and now they are all dead on even at 40 yds.
Bring on the deer!

Neither of thesestatements are true! No helical is necessary.See the chart, check your arrows, check your shooting form, shoot other types of broadheads. If the pattern countinues check your bow over for proper tuning or take to the local proshop for a check-up.
No amount of helical left or right will fix any of the above errors..
Good luck.
