Which ever one you can afford. I have the more inexpensive model, and in my opinion, I am getting the same results as the expensive models. Just shootem and then decide, can't go wrong with any of them. The only one I might shy away from is the Super Tech.

I own a 2003 cyber tec, I own a 2002 havoc tec, I own a 2004 ultra elite I own a 2003 Serria tech.
The one I shoot the most consistant with is the Serria tec. It is the least expensive of the bunch. I also hunt this bow exclusively now.
Second was the havoc tec another short bow and it is a good shooter.
thrid is the Ultra elite; for some reason I have trouble with longer bows, maybe because it is heavier.
fourth is the cyber. this one does not appear to tolerate any form flaws. I shoot it a lot to work out those flaws.

Of the ones I shot I like the xTec. The razortec would be my next choice.

I agree with WIhunter, I shot several bows from the Hoyt line-up and narrowed it down to the Xtec and the Razortec. I eventually upted for the Xtec and I love it. I ended up putting a Muzzy Zero Effect rest on it and that bow is Smooooooth and quiet.

Redneck

If I were to buy a new bow today, the Hoyt Xtec would be at the top of my short list, no matter what brand/models I were looking at. Ultratec would be up there as well.

I've been a darton shooter since 96. But this year,i sign on with hoyt on their shooting staff. Beleive me it's the X-tec, That bow shoots like a 40 in. bow .I shot with one for 3-d , i did so well with it i bought anouther to hunt with!

Thanks guys, you all helped me out a great deal. I was strongly leaning towards the X Tec, now you all have reassured me that it is the right choice by majority. Thanks again.
