Update! After talking to Bowtech Monday I found a package plastered to my fence(west Texas wind) and the mods are here! Installed the IF6(28") and braved the wind and took it outside and gave it a try...so much better! May shoot indoor this weekend and chrono both bows. Do have a tech ? for the group...would changing the d/l change my pin settings? The pin that was 20 yards is dead perfect at 30 now! If MeanV2 answeres the question firstI'm gonna order a sts from him!
