HAVE YOU HAD ANY TROUBLE SWITCHING FROM MECHANICALS TO FIXED BLADES WITHOUT SWITCHING GRANS.

If your bow is tuned right you should have no problem at all. Last year I shot both the Thunderhead 100's (fixed)and Spitfire 100's (mechanical) and both shot the same. This year I am using the G5 Montec 100's. Great broadhead, very tough and all one piece.

BigJ12 said it all. If your bows tuned you shouldn't have any trouble. I was shooting Spitfire's and had them grouping pretty good but bought some T-heads and Muzzy 4 blades and they didn't fly right. Made some adjustments and got both the fixed and the mechs flying true. The Muzzy's group pretty good but don't seem quite as tight as the Spitfires and T-heads.
