Ultra-EFOC, Heavy Bows and Long Draws

I’ve been reading, for the last 2 weeks, all of the older posts regarding the EFOC an Ultra-EFOC arrows and I’m sold. I REALLY want to give this a try BUT I’m confused as where to start. A 70# @ 31″ bow draw length combo is not too common, although I have seen others reporting this as well. Suggestions needed would be strongest lightest shafts others have found using these numbers. I’m not too excited about reducing my draw weight (ie: buys other limbs or a new bow) in order to find an arrow at 31″ that can withstand an Ashby head up front. I’m open for suggestions and look for more amazing discussion on this topic. Thanks to all who have weighed in before.

Pikeman — You a mighty big boy! 😀 While I can’t help with shaft stats that grand, it seems obvious that your problem getting EFOC will be finding a shaft that’s both strong enough and light enough at 31″. Almost certainly will have to be carbon, so you might hit the websites of some of the leading carbon makers and look for sizing charts. If all else fails, with your bow weight and draw length, and a good heavy single-bevel head and heavy shaft, I’m better you could shoot through anything even without EFOC, though I have witnessed its magic for myself and applaud your efforts to attain all the best stuff in a single package. I’ll be watching to see what others here have to say. Homer

I shoot a 32″ arrow @ 62 lbs. I have had to go to carbon> I currently use Grizzlystik alaskans with good results. There safaris are actually to stiff for my set up even with 315 grain head. Arrow dynamics hammer head series should also work. I am planning on testing them out this summer after turkey season is over. For EFOC when you cannot cut much of the shaft for tuning the tapered shafts give you a little more flexibility on spine.

My experience is that an efoc arrow is less sensitive to spine. The thing to remember is excess weight in the shaft and feather end rob the arrow of forward weighting.

I have used gold tip arrows with the most success. I have tried the tapered arrows and not gotten good results. But each to his own I suppose. Gold tips are a good deal as far as carbons are concerned.

I used to be a Carbon Express fan. But I found the gold tips were better for me. I attribute it to the fact that the gold tips are about 2 grains/inch lighter…

My other recommendation is to shoot the arrows full length if you can. The longer the arrow, the more stable it will be.

Autumnman: That’s what I’m shooting now. I have both the Safari’s and Alaskans and they both show weak (nock left) during flight with the AB 315gr field tip on them. I’m contiplating trying to build some IF Griz sticks. Hmmmmmmm

I would start with either Easton Flatline 340’s or Goldtip Ultralight 300’s. They have the fewest grains per inch, making efoc easier to obtain.:wink:
