Arrow flight is good with tips from 75 to 125...there is just way more arrow drop with the 125's...probably 8-10 inches difference at 30 yds...If I use the 75's I could site in one pin to be dead on in the low 20's and use it from close in all the way out to 30 where its only about 2 inches low if that....I'm gonna try and tweek things though and see how well the 100 grainers shoot before I buy anymore.
