Re: TAC 15i limbs
Sounds identical to my own experience.
I purchased my TAC15i from Len for Christmas last year as well, but those orders didn't ship until late January, so I received mine and immediately began working on set-up, trigger replacement and a number of other changes before ever even trying to shoot it.
Everything outside was frozen cold and windy, so I didn't try shooting mine until about April of this year.
Once April came around and started using it, I was on it almost every day for hours, so I rang up a lot of shots very quickly. I was also doing a great deal of testing indoors at a large indoor archery facility in New Jersey, where I had some great help and support from a few good friends that either sit on the board for Easton Archery or who were engineers or pro shooters that I've competed with and known for many years.
They were gracious enough to help out and lend their advice to much of the testing I was doing to sort out some of the grouping problems that I was working on with Super 91, Okebowie and a guy named Konrad. All are great guys and very knowledgeable, so we had one of the best knowledge based teams working these problems that I've ever had the pleasure to work with.
It took a few weeks of testing work and a lot of documentation to nail down the issues, but we finally nailed the problems. They are all documented in my articles under "PSE TAC15/15i Undocumented Information".
I had limited experience with the TAC15 Crossbows, but over 40 years of experience with competitive archery and having an engineering background I understood well the dynamics of arrow flight, so it was just a matter of applying my background knowledge and skills to this crossbow. It seems I've been involved in many of the problems that shooters are experiencing ever since.
My goal was always to reach out and help as many other people as I could and at the same time spread the knowledge and educate them at the same time. It's my way of giving back to a sport and hobby that's been good to me over my lifetime and hopefully others will enjoy it more as they learn more about it.
