RE: field points to broadheads
Personally.....I would probably have went to a 90 grain and shot 100 grain field points !
And.......it's not recommended to heat carbon shafts.....it weakens them (from what I've been told). Also if you can turn your broadhead after they are heated......I would be skeptical of what kind of adhensive was used ! Carbons usually require a good epoxy or something similar ! Hotmelt is usually used for aluminum shafts !
And .......you don't have to line up your braodhead with your fletchings.......a lot of people like to........but it makes absolutely no difference in my experience .
The only way your going to get excellent flight with the Muzzy's is to have your bow tuned, arrows spinning true, correct spined arrows, and have your shooting form down ! Muzzy's will fly fine.....don't get me wrong......the above is true of any fixed blade head IMO !!
Good Luck !!
