I'm considering trading my ACS 64" limbs for a set of 58" limbs.  Just wondering if anyone has compared the actual performance differences between the shorter limbs and the longer ones?


Thanks,

Allen

Allen,
When did you start shooting an ACS, bud?  I thought you were a "recurve with a plunger" type of guy....

Tom, I had an ACS last summer and sold it like a dummy. I have just been re-united with another one!!  I guess I needed a break from all the high tech stuff.....LOL

Roger that.

Allen, I have owned both and prefer the 64 in. The 64's are smoother on the draw and there is a noticeable difference in performance between the two.

Allen,
 It has been a while back and I can't remember for sure if it was John that said it or not, so I won't quote him as my source, but at that time, I remember it being said that the 64" limbs performed the best, but I think that was between their 62,64,and 66" limbs, before the shorter limbs came out.  Of course, the difference was only 1 or maybe 2 fps difference.  I have always preferred the 64" limbs, but for me it was how smooth they felt rather than the additional 1-2 fps.  Depending on your draw length, you may hit the sweet spot with a shorter limb and get a little better performance, but I think it will be minimal, but that is just my opinion and not based on actual data.  John or Larry would definately be the ones to ask for sure and it may jsut come down to your personal preference.
Take care!
Chris

Thanks guys! John H just pm'd me and said that I should see very minimal difference in speed.

I have a set of 58's coming to me to try out tomorrow (from Floodman on here), and trade for if I like them. I just love this site!!

I have a set of 58" and a set of 62", both same poundage. I will try to shoot thru chrono tomorrow and give you exact speeds, both with a light and heavy arrow.

I had some 64's and traded for some 62's ... I like the 62's a bit better just for the handling a shorter bow. Performance seems very similar.

I did talk to a fella at the Western States shoot this year that had 58's and did not like them because he did not shoot them as accuaretly, and this fella could shoot ... so I would value his opinion.

I love the ACS, most accurate / smooth bow I have ever shot. Mine is a 55#'er

I had a 64" one piece, it was the best shooting fastest long bow i have ever shot.  I would stick with that length.

I just want to make sure we're talking apples-to-apples.  A 58" bow based on our 14" riser will fall a few fps short of a 64" bow based on our 14" riser.

Our NEW DESIGN 58" bow (mounted on the purpose-built 12" riser) will be a match or very close to a match for our "gold-standard" 64"/66" bow.  The limb design for the new super-short 3PTD is totally different from the limb design for our original line of bows.  

Don't get me wrong - the 58"/14" limbs are quite good.  But they won't be as good as our 64"-66"/14" limbs.   The 58"/12" new-design bow WILL compare very favorably with our 64"-66"/14" limbs.

It took almost 3 1/2 years to come up with a truly short bow design with which we were fully satisfied.  The result is the 56"-58"/12" bow and the 60"-62"/12" bow.

John

Thanks again John, you guys are awesome!!

John can you explain what 56-58/12 or 60-62/12 means? Is it the limb length that makes 4 different lengths? Thanks.

Katman, sorry for the confusion.  My shorthand method of describing which bows I'm discussing.   It's the way that Larry and I often identify which bow we're talking about.  

Our new design, short, 56"-58" bow has a unique limb design that's optimized for maximum performance based on a 12"-long riser that ONLY fits onto those 56"-58" limbs.  

Our new design, short, 60"-62" bow has a unique limb design (different from the 56"-58") that's optimized with a different-designed 12"-long riser that ONLY fits onto the 60"-62" limbs.

If we had made one 12" riser design and mounted all four limb lengths on that one riser every one of them would have been sub-optimal - a compromise.  We didn't want to compromise so we made the limbs and risers optimal for each other (mostly has to do with the proper limb mounting angle for each bow design).  That's why each 12" riser mates only with the length of limbs that are right for it.

For shorthand Larry and I refer to the 12" riser designed for the 56"-58" limbs as the 12-56 or something like that.

Hope this helps a little.  Our website probably does a better job of explaining this than my feeble attempts here.

  John always takes the time to respond!

I haven't shot the shorter limbs,but I like my 62" limbs over the 64" limbs I had.They just seem to feel and fit me better,these are on a 14" riser.

Here is what I found today.
I have a 14" riser and a 18" Apogee (A&H) riser.
I have a set of 58" and 62" ACS CX limbs, both are 40# on the 14 " riser and 36# on the 18" riser.
So, I can shoot several combinations of limb lengths and riser lengths in 40 and 36 lbs.
Here are the chrono speeds I shot today with two different weight arrows.
14" riser, 58" bow, 40lb, 8.1 gr/in = 187 fps
                         10 gr/in  = 171 fps
14" riser, 62" bow, 40lb, 8.1 gr/in = 191 fps
                         10 gr/in  = 175 fps
18" riser, 62" bow, 36lb, 9.0 gr/in = 182 fps
                        11.1 gr/in = 168 fps
18" riser, 66" bow, 36lb, 9 gr/in   = 187 fps
                        11.1 gr/in = 172 fps
                       
I draw right at 28" and shoot split fingers with a glove.
Not much difference in speed, seems the most efficient combo is the longer riser with lighter poundage. The highest speed was with the 66" 36 lb limbs @ 9 gr/lb.
All limb and riser combos are very quiet have and zero hand shock.

Thanks John!!

Perfectly clear now John, thank you.
