I will be ordering the 3lb Timney trigger soon so I can install it immediately upon delivery of a new TAC 15i. My dealer is fairly local and has done a great job in servicing me extraordinarily well over many years when purchasing many Mathews, Hoyt, Bowtech and PSE compound bows. Until his service has degraded I'm committed to give him my business. That said, I've already learned a wealth of information from this forum and intend to order as many of my components for the crossbow as possible from Len/Andy. The new trigger is my initial priority and I'd like to better understand which other improvements should be considered in order of priority with the primary objective of achieving ultimate accuracy in the 90-120 yard range. I'm assuming the need for the HHA Optimizer, going to the new drop-away(would also like to see reports on the new Firenock Micro rest that's coming before moving on the Ultra), new arrows/vanes Dorge has come up with.... or refletching the PSE arrows to a 3 fletch design, installing a mono-pod for hunting, etc., etc............. jon.henry and others that see this post would you please prioritize based on your infinite TAC 15i experiences the order of priorities up to and including what scope to consider down the road for the best in long range consistent accuracy.
