    A bit high imo, my Pantera's never went above 300 fps. As for Spikers speed, its just plain BS.

    I really need to chrono my bow - I would be satisfied with those numbers based on what I have invested in this bow and how well it shoots. That will give me an idea of where this really sits with the added weight on my string/etc. From there, might be able to use that info on one of the other higher IBO martin/rytera and get a better feel for what could be possible.

    Turning into a good discussion, really appreciate all the input.

    Its one of the biggest problems with forums when discussing speed, so many base what they are getting on a calculator like 'Software For Archers' which bases there IBO on manufacturer speeds. If you can chrono a bow with a few different weight arrows is gives a much clearer picture, just a pity they aren't more affordable.

    I got my chrono on the cheap, back when i played paintball! There are some reasonable hand held units out there too.

    I have a buddy that bought one of the stabilizer mounted ones - but he moved a few hours away. I might be going out that way sometime this fall or might get lucky and he might come back up this way. He was going to bring it last time he visited but forgot.

    Got a semi-local pro-shop that has a similar chrono that they have said they would let me "rent" There is also BassPro - but it is like $15 for the range and another $10 for the chrono rental ... not all that worth it imo.

    No it is not BS.!
    I've shot them thru my chrono.
    I've shot them them thru the chrono's at two local shops.
    It only varies by a couple fps between the three.
    And my '09 Firecat is 4-5fps faster at 62# 29" than the 61.5# AX.

    And to add fuel to the fire:
    My 60# '09 AX came from a Rytera dealer that is not only highly respected as a dealer/shop owner/tuner etc...
    but is also highly respected on this, and other, web sites.
    It was originally his personal bow.
    He had basically the same chrono results with it...
    I can look it up to be certain but I think he had it at 290 with a 390.

    Sounds close.... i get 285 with a 345 grn and 27.5 in draw at 62 lbs. The draw and aarow weight would nearly cancel i think.
