I just bought a new 55 pound bear grizzly. I will be shooting a 400 grain arrow. Bear manufacturing says you can NOT use a dynafflight string on it. Has anyone used a dynaflight string on a grizzly, NOT a super grizzly.

If you try, i would suggest reinforce the tips. I personally wouldn't . But i also use dacron on all my bows. I have not seen a need for a faster string.

from all that i am seeing I won't try it. the problem is in AZ. 20 yard shots are next to none. Mule deer and elk are 40 to 50 yard shots. That is why there is a need for the speed.

Your more skilled than i. 40yrd 50yrd shot with a 55lb bow is above my skills.

I practice at 60 yards all the time. Another little hint for every one. Every half hour pull your bow back to your ear and hold it for 20 seconds. That way if you have to hold for a few seconds it pretty easy.

The speed difference is negligible--even at longer distances. I like "FF" type strings because they have much less stretch/creep (even in higher temps) and are much more durable. I'd use them if they were slower for those benefits.

That being said, the only bows I've used Dynaflight on that weren't rated for it were selfbows. With padded loops, no problems.

So you don't think that would hurt the bow? How many more FPS do you get with a dynaflight string?

I once cronied a dacron flemish and a dynaflight 97 flemish, with a 600 grain arrow, out of one of my own designs ( an r/d , flat, traped, longbow made of Brazilian walnut, Osage and bamboo i developed years ago) 60lbs at my draw. Dynaflight was an average 182 fps. The dacron averaged around 173 fps. So we are looking at a difference of about .5 lbxft/s of momentum. I personally prefer a heavier string because i do not have to silence them and they are easier on your limbs and tips. I defex all my personal bow to where they are pretty quiet, and with my heavy hunting arrows i have no need for string silencers. Now to suggest that my bows would be louder with a fast flight string would not be honest because i do not use them. And when we cronied the two strings i can not recall much of a noise difference. But with a faster limbed glass lam bow there might be a difference. Besides, i am one of those people who does not change what has always worked. Also, i have enough dacron 50 to make strings for the rest of my life.

Ok even though we are talking about speed i haven't said anything about the obvious. If you can't hit the spot you are aiming at it makes no difference how fast the arrow flys. I have very little problem hitting the spot at 50 yards , but the extra speed is always nice to have. I am not a normal recuve shooter. I use a finger sling, i hold back for as long as 7 seconds. I had to improvise for my tab with a string wrist sling. When i let go of the arrow i pull through and touch my shoulder blade in the same spot. That causes the tab to fly off the finger. Hunting here in az. Is a real challange to say the least. I am not concerned about the loudness of a bow when you realize the sound of spead is 1136fps ( i think or close to it ). That means any animal can jump a string. I will be sure what i want to do this week when i get the speed checked. I think it will be 215 fps. If it is i will not take a chance with the fast flight.

I can relate. My land is in west Texas so we have to deal with lots of open space with few trees. I will not take a shot beyond 25 yrds. I don't quit have the skills for 50 yrd shots so i have to focus more on blind set ups and reading animal movement.
