I've talked to a couple guys that had the regular Nitrum and then quickly sold them to get the Turbo. Just wondering if there are any other differences besides more speed. Obviously at my draw length speed isn't an issue, so was just wondering if the regular Nitrum was "special" too.......or just the Turbo.

The LD model comes with different limbs so obviously could shoot differently than the others.
There really aren't any "speed bows" available to the long draw archer. Most all the long draw bows (32+) have their own speed ratings which are based on the max draw length of that particular bow. So if I subtract 20fps to get it down to a more familiar comparative IBO rating, the 34LD is really a 320 IBO bow. Much like my PSE Freak which had a speed rating of 353, but that is at 33" draw. Subtract 30fps to get to a 30" bow and IBO is only 323.
So while many new bows have come out in recent years to help the shorter draw guys equal the playing field as far as speed goes, for the long draw guys my 2006 316 IBO bow is still very comparable to the fastest speed bows available today for us knuckle-draggers. Not much has changed for us in the speed game. And as a knuckle dragger that had a huge advantage over short draw guys........well, we just can't have the playing field equaled.

LOL.
So beyond speed, it all comes down to fit, draw cycle, feel, forgiveness, and tunability. I don't foresee ANY issues for tuning with a yoke bow. How much valley does the bow have, and is that adjustable at all? I prefer a longer valley for hunting and a shorter valley for everything else.
