As I have gotten older, I cant stack my arrows the way I used to.

I normally shoot 100Gr heads out of my matthews FX set to 69# and shoot goldtips 5575's

I was wondering what benefit I would get switching to 85 or 90 gr heads? would the bow shoot flatter giving me a little more margin of error on range estimation?

Bow shoots 286fps (or was it 268?) now with the 100gr head. I would think I should have plenty of KE with my set up.

David, IMO You should leave it alone. I would drop down to 64lbs and watch them die just as quick. Don't worry about it. The best thing is to get it out, adjust the weight to what you feel comfy with and shoot, shoot, shoot. Good luck this year.

i have shot 80 and 85 grain heads for years...will shoot a little flatter, and you won't be able to tell the difference in performance from a 100gr

Thanks. I was mostly wondering how much flatter it would shoot.

It seems that my bow has slowed down a little over the years.

I had a 20-25-30-35-40yd pin and they all touched. Now I have a 20-30-40yd pin and they have enough gap that the 5 yd pins would have space. I guess the limbs have lost a little oomph over the past 8-9 years.

As I have gotten older, I have a harder time focusing on the target and seeing the pins clear enough to shoot tiny groups.

Remember when you reduce the weight of the BH , you stiffen the spine of the arrow and reduce the FOC too . You may have to re tune the bow to accommodate the changes in arrow flight .
I like a heavier BH for a little more FOC . I would stick with 100 gr.

Ill stick with the 100gr.

Don't want to have to recreate the wheel.

I am shooting well enough to be confident out to 25-30yds. I just cant bust nocks at 35 yds the way I used to.

Why? Penetration? Flight? Arrow spine?

Flatter trajectory at higher speeds doesn't always equal more accuracy . Arrow flight with broadheads become more fickle .

Key statement you made was as you are getting older,I too was shooting at a higher poundage (70 lbs), shoulder bothering me,just didn't enjoy pain with what was suppose to be fun to me.

Then with the new bow, I dropped to 60lbs groups are tighter and most of all fun came back into the picture!!

My advise is drop down some, it will still get the job done! ;\)

The best thing I ever did was got rid of my FX and bought a bow with a smoother draw cycle that was more efficient than the FX and easier to shoot .
They are nice bows , but the cam has a harsh draw cycle . The bows today are faster with a better draw cycle .

the higher speed on arrows will also magnify any mistakes in aim or form...why do you think target archers shoot such slow speeds.

When I bought my Switchback 3 years ago (or 4) I switched from aluminum arrows and 125-grain thunderheads to carbon arrows and 85-grain thunderheads and haven't had any issues. The deer I've killed didn't notice the difference either. I'm also shooting 70 lbs. now instead of 78. My old bow shot around 250 fps but I've never put the Switchback through one so I have no clue what it'll do.

heck I dont know. If 286 is too fast then It was probably 268. I remember a 2, 6,8 on the chrony, just dont remember what order!

I may have to dial down the poundage after this season. Im out of shape and cant hold steady as long as I used to. Havent been training like the old days either though. Going to start working out tomorrow morning to get the muscles back in shape for season.

I wouldn't mind a new bow but if it aint broke, dont fix it.
Besides I don't have the money for a new bow this year. \:\(
