I have been shooting 125gr Thunderheads since the mid 1980's and have had great flight with them. I don't see the need to change myself but since you are looking for something different I'd say look at Muzzy and the G5 Montecs. Guys around here have had great success with the G5's and my proshop can't keep stocked! I know the Thunderheads can be testy in high speed bows but if you have a well tuned bow they shoot like bullets! I get good blood trails and they are razor sharp out of the package.
