I have a heavier set of limbs that I will be getting this week for my recurve.  I am wondering if you all think I will need to get some stiffer arrows.  Currently shooting Heritage 150s left full length (32.5") with 145 gr tips and std inserts.  Shooting 42#@31.  I have both 150s and 250s and can't really tell a difference in how they shoot although I might give a very slight edge to the 250s.  New limbs will be about 10 lbs heavier - 52-53@31.  I am drawing an honest 31" so do you think the 250s will be ok or will I need to go with 350s.  Hopefully someone will have similar specs and can give me some direction.  Thanks for the help.

250's should work ok. You will probably have to go with just a standard 125 gr, tip..

i also have a 31 inch draw and have shot the 150s and 250s out of my 58 lb recurve.  the 250s are better for me at that weight (145 grn tips) my guess is you will probably be able to shoot either depending on point weight and how much speed matters to you.

Kellybender I shoot 41lbs@30". I have had good luck with 600 GT's. How ever the GT people recomend that I not use this arrow for hunting,as it is a target arrow. I am looking for another arrow.What is the finished weight on the 150 cx. Also is your recurve center shot. How the riser is cut makes a big diference on arrow spine.

I dunno Kelly, I have a full 32" draw and on my 55# bows I had to go with the 350's

No need to go to the 350's, they would be over spined.  If you where shooting over 70lbs then use
the 350's.

The 250s spine is over 80# with a deflection of .373  You are shooting at 62# with 31" draw. So with that tip weight you should be fine. You didn't say what you are shooting though. Is it a longbow or modern day recurve...?

Looks like we are all over the place on this one.  I'm shooting uncut (32.75") 250's with 100 gr brass insert and 175-200g point.  This is out of a 59 @ 32" - high performance longbow (Shrew).

My CHekMate Crusader longbow likes the 250's also (56# @ 32") with 225gr up fromt.

Looks like you got some experimenting to do.  Think about getting a pair of test kits (one is only 2 of each arrow - doesn't to a thing for tuning) from someone like 3-Rivers, and do some playing.

Thanks for the help everyone.  I didn't think about mentioning the specs on the bow.  It is a Rick Welch recurve....new in Nov 2007.  I have been thrilled with the performance of the bow.  The 150s I have now weigh about 545gr with 145 gr tips and I am pulling 42@ my 31" draw.  Speed is around 165-167fps.  I am not as concerned with the weight of the arrow (150 vs 250) as much as getting them tuned to fly like darts.  I would prefer to shoot the same arrows that way I could just shoot the same arrow regardless of which limbs I shoot.

Because of the spine of the 250s you will be fine with them for the new heavier limbs. You will have to bare shaft them and see what kind of length will work for you with the tip weight you want to shoot.
