helical or straight vanes
 

i shoot a 2003 patriot left hand now last year i shot right hand 2002 patriot anyway i shoot at 30 inches 60# beeman 400s at 29 inches arrow 410 grain at 272 fps. i have shot with helical vanes 4 inch very noisy and with straight vanes pretty quite compared to helical. i will be shooting fix blade t 100 rockys pricee but nice head. this will be my elk setup for this year.i want to get good arrow flight want to use helical but to noisy in flight. if i up my arrow weight some and get down to 250 fps will there be any differants in noise. or am i stuck tuning with straight vanes i don' t want to use feathers to many problems and noise with them. would going with 5 inch straight vanes help any Thanks guys

Not to dodge your main question but have you considered either reducing the degree of the helical or going to an offset fletch instead of either a straight or helical?

i have notice that the straighter the flecth the quiter the arrow flight. i just want to starte out with something reasonaly quite before tuning.

Try shooting your broadheads with straight vanes. If they fly straight and group well at various hunting distances, then go with the straight. If you encounter erratic arrow flight and grouping, try the offset. If you still encounter erratic flight and groups, you may have to use the helical.

In my past experiences broadheads tend to plane with straight fletch a cause innconsistant grouping, especially at longer distances of 30 + yrds. Putting a spin on the arrow with helical helps counter the planing making for better arrow flight and grouping.

Noise with helical fletching may be something you have to give into to get accuracy. I have never bowhunted elk, but the noise from the helical does not seem to cause misses when shooting at whitetails.
