These are some very informal numbers.  The chrono used has showed an average of 8 fps slower than another one I have used.  I am sure it could be lighting, calibration and a host of other things. The faster chrono is not available at this time to compare. This is what I got Saturday.

Whisperstick Mojo 53@28 60" pulled to 30" where it is 59@30".  Osage and yew limbs.

535 grain axis        196 fps.
610 grain axis        186 fps.
This was an average of six shots with the highest and lowest thrown out.
I shoot split finger with a tab.  This was done with bow hush and hushpuppies installed.  These are the same arrows just went from 125 grain heads to 200 grain heads.  The arrows are a shade weak with the 200 grain heads.  The best thing of all is this sucka is quiet!!!And I beleive she likes heavy arras

sounds right jd makes a great bow and very fast toooo

Very impresive numbers bud,,He left me a teeser pic today in an email,,JD has something special about his bows,,any pics,,MAN LAW OBSERVED,,LOL,,J

Yessir, those are some fast and quiet bows.

ditto...after some tweeking I got good arrow flight MY 53# loves a 63-66 Woodies, WHAT KIND OF CARBONS DID YOU SHOOT??? I shot vaporwoods, and Legacy's all got great arrow flight ...My only regret was not ordering this bow in higher poundage ...smooth , quiet,...JD is great guy to work with...Mark         IM Happy happy...what number AXIS???...this is bowhunters bow ...

Axis 400 with 100 grain brass inserts.
I am most impressed with how quiet this bow is.  I still need to do some tweaking on spine but these are real close with the side plate built out a little.  Most bows I have shot showed a 10 fps difference every 50 grains.  This bow it is 75 grains.  I like the idea that she likes heavy arras.  This is a true hunting bow!

That should work real fine

Luv my Whisperstik !!!
