i have had the wisker biscut for 4-5 yrs. just changed my biscut this year. i use feathers, i spray them and the rest with NO SNOW. i have never ever had a freeze up. 5 arrows touching (the arrows not the feathers) at 20yds. how much more accurate can you need unless shooting purely for compitions. i shot around 1500 shots this year then replaced my feathers, they were shooting fine i just had the time and they were looking alittle worn. ive seen feathers shoot straight even when one or two are really worn out or missing chunks.
