What's up? I shoot a jennings g2xl and it's set at 60 lbs. I use muzzy 100 grain 3 blade broadheads and didn't even have to change a pin on my sights. For sights I'm using a trophy ridge 5 pin. This combo has prooven to be very accurate with both field points and broadheads. For your setup I would stick with 100 grain broadheads. Also shoot 100 grain field points. I think the brand you should use is whatever your comfortable with. I've had good luck with the penetration and flight of muzzy's so I stick with them. If thunderheads have produced good results for ya stick with em. Congrats on that 6 point you got.
I haven't been so lucky this year but I'm goin out tomorrow morning. I think the second phase of the rut should be happening or close to happening and with the dusting tonight with colder temps maybe!!!! Well hope this helps ya. Good luck.
