Hi Ronmc,
That was Dorge that you were speaking about and yes, he's a very interesting fellow. He also stands behind everything his company produces, so if there's ever a problem, he'll make it right.
I can't recommend another arrow to replace the PSE TAC15 Arrows at this point. My reasoning is as follows; Firenock produces a new carbon shafted arrow that's light years ahead of the PSE TAC15 arrows. They are supper Straight, perfectly uniform in shaft wall thickness and diameter. They are perfectly round end to end, so they are in every respect an ultra high quality arrow that is also multi-spined and built on a woven carbon multi-layer composition. All this is exactly what we've been waiting for. The only problem is that the PSE TAC15 Arrows are spined correctly for the poundage and torque of these crossbows, at .0150.
The Aerobolt II's that Dorge is having produced are spined at .0250, which make them a bit softer in spine than the PSE TAC15 Arrows. Basically this means that they will work well when equipt with an 85 grain field-point or broadhead, but as you add any weight to the front of the arrow it requires more spine stiffness to be able to handle more mass weight.
I can't tell you if these arrows can handle anything additional because I haven't tested his arrows out at long distances yet, nor have I tested them with 100 grain heads or greater. They are very expensive regardless how good the quality of the carbon is, so nobody I'm aware of has any good solid testing statistics to validate if his arrows will or won't support a range of different weight heads and still fly well.
Nobody else industry wide has come up with an arrow that is well suited to this crossbow, yet. Both myself and Super 91 have built sets of arrows using the PSE TAC15 Shafts that fly extremely well and are as durable as possible. Each arrow is precisely matched for both spine characteristics and balanced to within 3 100th's of a grain for weight consistency. This is how we've both managed to produce incredibly tight groups at up to 100 yards. It's the only way I know of that it's possible unless somebody is shooting the same arrow each time they take a shot.
I taught Super 91 the process of measuring spine, aligning nocks and then how to weight balance his arrows using an electronic grain scale and epoxy. He's a bright guy and learned well.
I also found that the Whisker Biscuit Arrow Rest causes a series of problems due to inconsistent friction it puts on the arrows each time they are fired. It is also responsible for constraining the natural oscillation of an arrow as it is fired. This effects consistency from shot to shot, so I changed to the QAD Style Rest to eliminate these restrictions.
I personally think it's best to make changes slowly and sequentially so that you can measure the gain or impact of each change until you achieve your desired accuracy level. There's obviously a big difference between a tack driver and an average rifle or crossbow. Each shooter needs to find at what level their weapon is performing to meet their individual needs.
Even with a Whisker Biscuit Style Arrow Rest, these crossbows should be able to produce a 3 inch group at 60 yards any day of the week as long as your arrows are correctly matched.
Also, take a very close look at your four vanes on each arrow when they are loaded on your crossbow, just prior to a shot. I found that many times, during a shot, one of my vanes would come in contact with the underside of my upper Weaver Rail. This would cause launch variations that again were undesirable for consistency, so I shortened my uper rail by 2.75" to eliminate this problem.
This modification also allowed me to shoot 3 vane configurations, if I wanted, but the main factor was it corrected a contact launch problem.
After all the changes and all the experience I've gained over time on these crossbows, I personally think that the TAC15 version has one or two benefits over the TAC15i version. They deal with the silencing capability of the unit and the fact there are so many different AR-15 lower units that one can chose from. Otherwise, both can be made to shoot extremely accurately with a little patience and work.
Regards,
Jon
