Greg I purchased a used 2007 Bowtech Guardian. But I am afraid the draw weight is going to be too much for me ( I am getting old) Can you give me a ballpark figure on a new set of limbs I want 50-60. I love this bow but I know I will have some problems in the stand if I am cold or stiff. But I got such a deal I couldnt turn it down.

Royak,
I'll pretend I'm Greg........LOL

How much weight do you need to knock off that thing? The reason that I ask is that the Guardian has super long limb bolts which allow it to be turned down to the point where you can actually relax the strings for work without a bowpress.
Even if you need something like 56-57# or so on those 70# limbs that really shouldn't be a problem. If you look at the holes in the riser where you can see the limb bolt threaded thru, just make sure you don't back them out to a point where they start to leave that upper smaller hole (thread bolt sight port)

Turn it back to 60 and see how she feels, You won't change the efficiency enough to warrant a new set of limbs if you can handle the 60#.

I'll pretend too to be Greg,

Royak, on my 82nd, I turned it back two full turns and it dropped from 70lbs to 60, I turned them back in 1/4 turn each to 62 pounds. It will clearly drop more to lower than 60 lbs. The Guardian is even moreso adjustable. I think Matt offers up some real valid points. Limbs are never cheap. Look at the price of a new bow, much of that is in the limbs.

Looks like Greg's gotcha taken care of! [8D]

Seriously, if you have any more questions after the above advice... shoot me a PM or I know you've got my e-mail too.

Thanks guys all of you I have been shooting 60 for years and when I got this bow the guy said it was 70 I havent checked it yet but I did back it down some but was afraid to go to far as I dont have a scale ( my x kept mine) I am not sure what the poundage is now but I do know it is still too heavy for me right now. I will try what you said Matt. I really like this bow super quiet and no vibration at all. But I do know after a few hours in the stand in cold weather any bow gets harder to draw it back.

If it's a Guardian Roy, what I would do is just bottom the thing all the way out to start with... probably 70 or 71. Then I'd make two turns ata time on each opposite limb bolt, making sure that you don't skip one... It's probably going to take at least 10-12 turns on each thread due to the close threads used on that model's limb bolts to get her down in the lower 60's. I suggest bottoming it out to start with so that you keep the tiller as close to even as you can while you're adjusting it down.

After you've loosened that limb bolt 6-8 times on each end, I'd try it... turn it down one more time, try it... turn it one more time, and try it. Keep doing that until you're comfortable with the draw weight. Like Matt said, if you used to shoot 60 regularly, you're not going to take that down too far before finding a comfortable draw weight for you.

Thanks Greg I will try that I really appreciate all the help.
