Ok so I got to order new arrows and this chart tells me what I need to buy. I do and I think this chart is off. My set up 2013 hoyt Spyder 30 60lbs draw 28 inch draw. It said use 400's but my bow shoots 340 better. So what is a guy to do? Sent from my iPhone using Tapatalk
with out knowing the length of your arrow ad your point weight I cant help you much. Although the easy answer is if your shooting 340's better stay with em.
400 sounds right for your set up, especially 60#@28", 340 sounds a tad too stiff. Go to Pinwheel Software - Software For Archers, Tapes And Charts, Shaft Selector and download the free trial and put in all of your info, see what it comes up with. V
I"ve found those arrow charts to be a bit off at times. It seems today's bows are putting a lot more pressure on the arrow with the harder cams we're seeing. IMO, I would go with the 340's. Broadheads, especially fixed heads, shoot better with a stiffer spine. Plus, by going to the 340, you can play with point weight because you'll have wiggle room. I shoot GT Pro Hunters in 340 out of a 28.5" draw, 64lb bow. I use 100gr heads, but this last season, I added 50gr insert weights to the front end and it gave me an FOC of 16%. They flew well before, but are lights out now.
