Arrow Spine Question

[RM81]

Hey everyone.  New guy with a question about arrow spine.

I have a lighter bow that I'm practicing on, and then going to move up the weight once I get basic form down.  I'm practicing around 40#, and have another bow that is 50#.  According to Gold Tips arrow selector chart, they recommend two diffent arrows for these weights.  A 3555 (.500" spine)for the 40# bow at my length and draw.  And a 5575 (.400" spine) for the 50# bow.  I'd like to just buy one set of arrows.  Would I be ok just getting the 5575's and shooting them out of both bows?  Or do I need to just get both sizes according to their chart?  I realize I shouldn't shoot the 3555's out of the 50# bow, but what about shooting the 5575's out of the 40# bow.  Any help or recommendations is greatly appreciated.

Well, you could but your arrows would hit about a foot to the left of where you are looking for a righty I think ? I am a lefty. The 55/75's would be way, way, too stiff for you in spine. You need arrows matched to the bow. You should bareshaft to get things matched correctly.

Go with the 35/55's for both bows.  You can make adjustments to the point wt and lenght to get them to fly good out of both bows.

35/55 will work with  both bows,just takes a little effort.

ended up getting a dozen 3555's.  I'll cut them just long enough to use broadheads.  thanks for your suggestions.

If you had asked that question w/o the comment about the chart.  I would have told you you need .600 for the 40 LB bow and .500 for the 50.  That is unless your draw lenght is over 30.  Go with the .500.
