I expect to buy a Bowtech Extreme VFT. I' m not sure whether to order the 60# or 70# limbs. I could easily shoot the 60" bow maxed out at 60#, but would like to shoot about 63-65# now and possibly more in the future. According to Bowtech' s specs, you can adjust the weight down approximately 10#. My question is, will shooting 70# limbs cranked down to 63# adversly affect the performance of the bow? Will the bow shoot better cranked up to the rated weight of the limbs? (i.e. will a bow with 60# limbs maxed out at 60# shoot faster than a bow with 70# limbs cranked down to 60# or will they shoot about the same?) Also, are there any other considerations that would affect performance shooting a bow less than the maximum rating of the limbs (i.e. more vibration, hand shock, etc)?

Any advice would be appreciated-
Paul

Cranking down the limbs will be less performance. You want to keep your limbs and draw weight as close as possible.

My best-friend has a EX-VFT. He has the 60# limbs maxed out at 63# He has a 28" draw length, with all his goodies on, and shooting a 27-1/2" Easton Carbon Epic (with 100 grain field tips), he is getting between 260-270 f.p.s.

BM, I have a 70# VFT cranked down to 64lbs 28" draw with 27.5" GT XT 5575 100grn tip, all the goodies and I' m getting 271fps

Birth cert. was 307fps at 28" draw. 71#

I have a VFT 70 # limbs cranked up to 72#. Shooting 28" 390gr GT 5575 XT' s @ 291. The bow will perform the best close its peak weight, but you don' t want the limb pockets maxed.

My VFT is 70.5 lbs @ 29" and shooting 367 grain arrow at 306 fps. Birth certificate says 317 fps

Dont kill yourself , rarely have I seen a 60 lb bow that was 60 pounds maxed out , most are 63 64 so your getting what you want with a 60 lb model

Most people are not good enough shooters to tell the difference. I would not sweat this decision.

I would go with the 60# bow, max it out and forget about it. If you have the 70# option you will always be wondering about cranking it up. Some people can pull 70 with no problem. I used to, now my 70# bows are pulling 65 and 67#. If I was maxed out at 63-64# I' d be just as happy. With the speeds/power generated from todays cams a 60 is all you need to kill deer with plenty to spare.

Thanks everyone. After much consideration, I decided to go with the 60# limbs. Wouldn' t you know the dealer only had 70' s?? Anyway, I' m sticking to my decision and ordered the 60s. I should be picking it up next Saturday.
