Has anyone tried it how dit it work out? I am thinking of setting a Hoyt 737 up with Spirals but im not sure if it would be worth it. I have had C2 cams on it and liked them pretty well. Hoyt says it wouldnt work well with the short limbs but I know someone on here has tried it and im wondering how the draw cycle felt.:darkbeer:

I have tried a set of C2s on my 737 and I like the way the draw cycle felt it just raised my poundage 10lbs but I have a new set of limbs coming to correct the poundage. I like the back wall on the spirals though.:)

spirals are even worse, thats why they came out with the C2. going from cam1/2 plus to c2's will increase your poundage about 10 #.same thing with original cam 1/2 to spirals. the same model bow with same poundage draw equipped with c2's and one with cam 1/2,the deflection of the limbs is less on the c2.

So what you're saying is that spirals will raise the poundage even more than the C2 cams did. If so how much am I going to need another set of limbs ? This experimenting is getting costly. :)

. . . . going from cam1/2 plus to c2's will increase your poundage about 10 #.same thing with original cam 1/2 to spirals . . . .
I don't think that is accurate -- I'm pretty sure the draw weight generally goes down when switching from the old Cam-1/2 to Spirals . . .

I know for sure it did when I did that on an Ultratec XT-3000, 70-pound bow with original Cam-1/2 peaks at about 67 with Spirals (I also increased the draw length at the same time; I'm pretty sure at the same draw length the draw weight decrease is bigger)

So back to the original question -- X7 with XT-1000's and Spirals -- how did it work out for speed?

I will second that. Going from cam.5 to spiral or C2 is a decrease in poundage not an increase.

You are correct I made the change from cam.5 to Spirals on a Ultra Elite and it reduced the poundage by a few pounds. I am now wondering about going from C2s to Spirals what will it do?

your right, I got it backwards 60-70# limbs with standard cam1/2 will be about 50-60 lb limbs if cams are switched to spirals.

I did a Vantage X7 with Spiral conversion recently. After doing it and testing it decided it really wasn't worth it, I think I got about 7fps and I prefer the feel of the Cam 1/2 Plus anyway.
I did a full report on it at ArcheryLive.com including how I worked out the string lengths.

dude the spirals are gonna be even worse,Im tellin ya. Thats why they came out with the C2,almost all the speed of the spiral with less harshness.

I have owned a Ultra Elite with Spirals I liked it pretty well for a target bow. I am leaving the cam.5+ on for hunting season and then I will try the Spirals out. I was just curious how they performed on the XT-1000 limbs. I prefer Spirals over the old cam.5. My last bow was a X-Force so harsh isnt a issue. I shoot very hard back tension and usually build draw stops on all my bows for a rock solid wall. I am shooting #70 now but I will shoot #60 with the Spirals. I have spoke with Dan Macarthy several times and he said he didnt know how it would turn out on a 1000 limb but its the way to go for speed in a short DL.
