View Full Version : Axle to Axle vs Speed

Ok guys, I know long axle to axle length is supposed to be a good thing in a target bow, yet at the same time speed is a bonus on a 3d bow.

How important is one vs the other in a 3d bow. For example the bowtech Guardian is 33 3/4" ata going 321-329, while the bowtech Commander is 37 1/4" ata while going 310-318fps. Likewise the APA Black Mamba X2 is 33 7/8" ata going 340 while the APA Anaconda is 39 1/2" ata but only going 330.

I realize there is also a brace height difference which is supposed to make the faster ones tougher to shoot as well, but basically the question is this:

Is the longer axle to axle worth the 10fps or not?

I know this is a somewhat subjective question so please give your reasoning behind answers if possible. Thanks so much.

This is a debate that some others may chime in on as well...

I have shot a variety of bows and the ones i use for 3d are cooking about the 300 fps mark....

These are from my 31" ATA Outback to my 43" Martin Impala... my current A7 is about 38" ATA.... ATA has little impact on speed!....

Whne it comes to "forgiveness" i have found brace height is very critical and has mor impact on left to right forgiveness...

With shorter ATA I find there is a tendency to cant and this can be corrected with using a level....

Now an interesting concept is what I call true ATA with some of these parallel limbs and huge wheels when bow is drawn string angle is decreased with large wheels which act like a longer ATA bow..... But these big wheels are very susceptable to "lean" which is what makes the Trykon "hard to tune" Hoyt will not accept or reveal the fact that parrallel limb bows are susceptable to cam lean.

Many of the new target bows..... not parrallel.... smaller wheels... and fixed yoke vs sliding yoke....must be a reason....

Shoot a bow you like that fits you and you will fid it will shoot the best for you.... USe a level and everything will be ok!.
