I bought a Mathews Monster XLR8 about 2 years ago and have been shooting very well with it. I use a QAD Arrow Rest, Carbon Storm Arrows (340's), and have it set to about 62 pounds on a 30 inch draw. I was wondering who else out there has the same bow and what arrows they use. I shoot at least twice a week with it, and i was thinking about tightening it up to 70 pounds on the draw. Any advice on the setup would be greatly appreciated. thanks.
Hey, welcome to the site, you should post up some pics of the bow, no real reason, just love bows. It sounds like you have everything up and running. My only thing is that after I turn it up that much I like to retune everything.
I have a similar set-up. I have a Monster 6 with a QAD at 58# with 29" 400 arrows. I'm hitting good out to 60yd. I was thinking of cutting the arrows down about 3/4 to 1" so I could get just a tidge more spine. But I've always thought if it ain't broke don't fix it and I don't have a good range at hand to **** around with tuning a lot.
I shoot a Monster 70# draw 28 1/2 inch. I shoot Easton FMJ's 340 as well. I currently use a QAD but I'm about to trade it in for a Downforce. I get alot of fletching contact on the QAD right now and its very disapointing. Currently the Eastons have to be fletched and tipped so I'm actually shooting a NO name arrow with an unknown spine..lol. But I shoot great out to 40. I'm hoping with the adjustments I make with the new arrows and the downeforce i'll be able to increase out to 50. I just have to get my hands on it first...freggin wars.
If you go up in poundage much at all, you're probably going to experience WEAK SPINE reactions. Those bows are "speed bows" and are rated for IBO weighted arrows, but it's hard to get an arrow that has enough spine to shoot out of those bows that is anywhere near IBO weight. I'd expect MOST guys shooting speed bows are shooting weak spines and mechanicals because they find they CANNOT tune a fixed blade BH very well. To the original poster, even with your current set-up, at 29" you need something in .300 spine to be stiff enough. Go to 70#, and you need a special order arrow in most shops!!!
Ohio is right with that 30 inch draw at 70# with this bow your gunna want to move to at least a 300 spine if not stiffer yet. I actually decided to go down 25 grns on my heads to 100 grn and I'm dropping my 70# to 60# for the season just to be on the safe side and so I'm not buying ANYMORE new Arrows.
The other BAD thing about having to drop tip weight to balance out your spine drops your FOC, and then you have low FOC which doesn't lend itself to good arrow flight. The tragedy of the speedbow is that the IBO speed isn't easily achieved, BUT, you CAN get a heavy arrow to flight pretty damned fast and hit AWFULLY HARD!!! You may not get a 350 gr arrow to fly 360fps, but you can get a 475gr arrow fly 300fps an hit like a ton of bricks!!! Comparatively 10 yrs ago a 300fps IBO rated bow was pretty fast.
As far as shooting weight. I have a Mathews 6 that I'm shooting at 70#and was thinking of lowering it to 65# just because it's more enjoyable to shoot at that weight and the bow is fast enough. Try shooting at 65# before going up to 70#. IMO Don't know why the photo is turned. It's taken with my iphone but straight on my computer.
I was thinking the same thing about the FOC. With dropping my tip wieght and having such a heavy arrow I know I'm giving up alot of FOC. But then I'm thinking well that arrows pretty heavy and it's still going to hit pretty hard. Maybe next season I'll spine in around 280, lighter wieght arrow and Heavier heads but I've reached my budget for the year
FOC makes an arrow fly SO much better, especially if you go from a LOW FOC to a HIGH FOC. My arrows are right around 14%, going to 14% from 10% seemed to make a significant difference in my arrow flight, especially at longer distances. Also those heavier arrows make that bow a bit QUIETER to boot, and are easier on your accessories, etc. on your bow because they absorb more of the energy reducing the shock to your sight, quiver, rest, etc. Sean, I see you're @ Ft.
