New use for Speed Pro arrows?
 

No Art, not high price tomato stakes... :)

It occured to me last night as I was contemplating the benefits and merit of the old heavy duty built 2 bladers, specifically Duggaboy's Silver Flame broadheads (I couldn't sleep, too much caffeine, wife had "a headache"). You can get this head down to 125 grains, but he 150 and 175 look way cool and are built like tanks. Not much elastic deformation going on with them, for sure.

Anyway, as I was mentally calculating the weight they'd add to my 375 grain finished arrow and the subsequent speed loss, it occured to me. Why not use the Speed Pro arrows to offset the weight?

Looking at their best, stiffest arrow, it weighs in at a whopping 6.2 grains per inch. My current shaft length is 26.5, so apples to apples I'd get 165 grains of shaft. Add 15 for an insert, 15 for a nock and 30 for vanes (or feathers and backweighting to preserve FOC), you get 225 grains. From their:

125 grain head= 350 grains
150 grain head= 375 grains
175 grain head= 400 grains.

Wow. I could use his 150 grain head and shoot the same energy and fps as I do currently.

Course, I have no idea what the advertised specs are of the Speed Pros's, or whether they meet spec or are more susceptible to spine degradation issues. I'd be very leery of switching from my ACCs unless these questions were firmly answered, so:

Anyone have any technical input on these shafts?

Trad guys have been using super heavy broadheads on carbon arrows for several years now, in order to get the weight up to a manageable level. They've been having good results with it, from all accounts.

Hate to let you know you're not the first to come up with the idea. [&:] But I guess I'll give you credit for being the first to think about doing it with Speed Pro's. :D

I'm not sure a whole lot of folks outside the HCA inner circle has done much testing on the Speed Pro's yet, and they sure as dickens won't give out any 'unflattering' info... assuming there is anything bad to report.

I have my doubts about their durability/longevity due to their light weight but, since I've never even seen one of those shafts yet, I'll not post on my gut feelings. Gotta defer to someone that HAS got experience with 'em.

Sounds very interesting! Good luck & keep us posted on your results. I woudl be curious what your FOC would end up being with a completed shaft with broadheads. Here is another idea for you, if you find that the head is a bit heavy a arrow wrap (crest) would give you a little better balance from the combo......granted not much but if matched with 5" vanes it could work out very nice and look really cool!

You knwo you really want to try it with those new Kodiak Grizzley shaft or watever they are that are super heavy carbons! Man it would be a slow rig but it should thump anything that gets in it's way! I know.....getting the speed is more fun!

I think we all need to pool our money together a get Arthurp a batch of those speed pro's for Christmas this year..................we all know he secretly wishes he could have a dozen

RE: New use for Speed Pro arrows?
 

Duggaboy tried these, I'm pretty sure, and found their tolerances, well, lacking :) He sticks to shaft inside a shaft to get heavy.

Arthur, yeah, I thought about just sticking them on my shaft as is, but since I backed the poundage down, I don't wanna dip my fps any lower than it currently is. Trade of in trajectory and performance, you know. Learned that from a wise old fart somewhere :)

Knowing how cheap, er, frugal I am, there is no way I'd pull the trigger until there is an abundance of un-biased experiences to banter about... :)

PM Vic (500FPS)..he bought some awhile back.

I would think FOC would be whacked (especially at your arrow length) without resorting to some major weighting on the back end...like Bohning 5" high profile vanes and a wrap & unibushing w/ G-nock

GoldTip has FOC calculator on thier website that will give a rough idea...just pop in arrow weight in gpi, & component weights for nock and point end

RE: New use for Speed Pro arrows?
 

Jeff, didn't Vics arrows warp into another dimension the first time he shot them?

Hard to get consistent data on their durability if so :)

I hear ya on the FOC. I assumed it would have to be dealt with, but hadn't thunk things through that far yet. Originally I was hoping the speedpro's would accept a g-nock and unibushing, and hoped the heavier NAP QSs would bring things back in line, but I'm reading the QSs aren't all that durable.

RE: New use for Speed Pro arrows?
 

Yeah..He had 'em cooking at 420 something FPS out of his BK.:D Bohnings are more durable than the QS...but not much..and they are heavier than the QS.

RE: New use for Speed Pro arrows?
 

Go ahead on! I know where to get weight tubes. ;) I don't know if you can find 'em in 32 1/2" length tho...

About FOC, like I said, I know some guys running heavy heads - like 190 gns - on Goldtips at between 18-20% FOC and getting good results. I couldn't swear to what'd happen if you bump up arrow speed another 70-100 fps though.

RE: New use for Speed Pro arrows?
 

Good question about the shaft & how well they hold up. I have yet to actually see one of these shafts at a pro shop in my area......makes you wonder.
