Frank,
Congrats!..didn't know you had a little one on the way...you better buy a BT now, cause once the kids come, that's all she wrote..you will watch the money go down the tubes in the form of poopy diapers & spit-up (you wouldn't freakin believe how expensive diapers are, and how fast they go through em)!
Well, I still see the ES as a viable option for you w/ only a slight diff in AtoA (which personally I cannot see making the difference between making a shot, and missing except in a extremely rare circumstance). The mass weights are similar if not favoring the ES a tad..my 2000 ES is lighter than the HTec in hand, I suspect the SandTrap models are comparable... but hey..you want, what you want..
RE: the DTI..honestly I've been having quicker & increased serving wear with the DTI compared w/ the old STI. My slide is set-up correctly for the Excel cam, and the problem started AFTER I had the DTI put back on correctly. I'm a bit dissapointed in that regard. W/ the WC cable I get a bit of discoloration, and my Q2 w/ TT 450 cable has had virtually no serving wear either....go figure..
The limb stop IS fantastic. One of the great things about all the bows I have shot w/ a limbstop is that they make you so much more consistent...there's no way you can draw any further(unless you are intentionally trying to break the darn thing), and on most onecams that's a sensitive thing..and one of the reasons I much prefer the original RL vs.the new models..it's still too easy to overdraw on the peg stop, and get some goofy shots. While the Peg stops are very versatile, I've come to dislike them from an accuracy (or forgiveness) standpoint for 2 reasons. First, the aforementioned "overdraw" circumstance and Secondly, the fact that unless you like 70-80% letoff you get reamed on the length of the valley. I sure wish Hoyt would go back to the original. Ah well... as I said..different directions..
Also the Infinity cam has the "deepest hole" I've felt. when you get back in the valley it's amazing how much tension you can let up and not have the string go anywhere..there's no middle ground..either you are way in or you are way out. For those who relax a bit as they anchor and then start the back tension up, it really is the ultimate. The Limb stop is one of those things that once you try, you probably cannot go back to any other system. I loved my PSE Durango, Fireflight, and Flash w/ LC's for that reason, and also my BM2000..it forces you (without being un-natural or uncomfortable feeling) to be consistent. Even compared to a onecam w/ a super solid stop on the track like the Mini-Max cam or a properly timed SL, it's much more consistent.
C'est la Vie
