Mobow, I have been shooting that set up for hunting for the past 10 or 11 years with the exception of last year b/c I was in a hurry and couldn't find the weight tubes. I am looking at being around 500 gr. with 270 fps for this year, in the past I have noticed that the heavier arrows do fly better, the bow seems smootherand I never got into the blazer deal to start with.....I am with you on that subject!!!!
