Borders are a decent buy if you like them. I have never tried Borders Formula fit so will refrain from comment.
I cannot speak to the Integra or the
ACE as I haven’t shot them. The Integra seem expensive for what they are. I have never even seen anyone shooting the
ACE limb. I’m sure they are fine but...
All the
Hoyt limbs from F3 through to the latest have all been at least OK.
I found the budget Excel limb very soft and clunky but the arrows went in the middle. Personally I wouldn’t (I had a light set after an injury)
The 720 was a good wood carbon limb. I kind of regret never buying a set of those. Can’t speak to the later 840 but I wouldn’t buy them as they have a stupid name.
Foam F4 should be very cheap now, around £100 to £150. They were a bit clattery for me... a bit noisy for me and a little more vibration than some but they shot well. F3 were very nice but I doubt you’ll find a set. Very very nice...
F7 in wood or foam was a nice easy to get on with limb. Would recommend both. They weren’t terribly popular but I never had any issues.
Quattro was a good limb also - I have a set of woodcore that are great. I had a set of foam core which were OK, shot very well but a bit snappy for my tastes - I preferred the wood. Quieter and nicer feel IMO. Recommend both.
Cant speak to the XTour, never shot them.
The Velos are fast and snappy. Not the quietest. Not the easiest to tune but shoot unbelievably when you get there.
Given that the best archers in the world have achieved only 10 points more with the Velos than they achieved with the F4, any of the older top line limbs will out shoot 99.99% of us.
if you can afford Integra then Quattro/Xtour are on budget easily. If you can find a decent set of 720s I think you’ll be happy there too.
Dont write off any of the MK F limbs if you can find a set at a good price. There are quite a lot of good deals on previous model limbs currently. Just be aware they will be heavier than
Hoyt on marked weight.
All of that is based on my experience shooting 32” x10 at between 40 and 44# in 27” risers (and 25“ riser for the Velos) with Medium and Long limbs (70”, 72”]
This applies for me in both HP and standard geometry
Hoyt risers But in HP I would avoid the F4 But the foam F7 was good. All of my preference is about feel, even the Excel shot better than me. All of the limbs have slightly different compromises on stability/Speed. Price varies for secondhand with condition and length/# combo.
Hope that helps ;-)
