I have Uukha Gobi short limbs on my Hoyt Satori 19" riser. The Gobi limbs are 50% glass and 50% carbon...and they have the best all around "shootability" for smoothness and good arrow speed, due to the "S" curve, which is similar to the super curl limbs. 💯
I don't know how the SX50, SX80, etc. compare to the Gobi model limbs.

I would recommend staying away from 100% carbon limbs, as most of them have a bad track record for breakage. 🚫 I've called around to several archery dealerships and have been told the same thing by all of them.

 

Honestly, if I were you, I’d just jump up in poundage with another set of the gold stars.

I have an older set of uukha evo2’s that I’ve shot to a pretty high level on my 27” GT. I’m pretty sure that if it weren’t for being mostly fiberglass, they would’ve broke last year due to 10’s of thousands of shots with them wound all the way in. I would not want a high carbon content newer uukha on a GT if I was going to use all of the limb pocket adjustment.
I now have GTL88’s that are a much better limb. These tune so much easier then my uukhas and are more forgiving.
I’d recommend staying with conventional limbs for stringwalking.

 

I think the consensus is that if you are walking the string you ought to steer clear of the Super Curves.

 

The Uukha S curve give you a softer back end and a little bit more speed.
I would buy another SX 50, but not another 80% or more carbon Uukha limb after breaking a couple

 

I'm not sure what I'm looking at (or for) when I compare the Uukha SX50, SX80, and SX+ limbs. Will a barebow stringwalker notice the difference in carbon content? Will a novice be wasting their money? Thanks in advance for any insight.

No and you are wasting your money in my opinion.

I own the the SX50 and Uuregs right now and I did own some SX80 which I sold and shot some SX+. They're sweet, no question, and all of them amongst my favourite limbs I've tried.

But the difference made to us, unsighted single stringers is only in the pocket. A little speed you might see but for me its doesn't justify the price.

 

My chrono says there’s no difference between SX50 and SX100 based on the very short comparison I ran.

 

Interesting

 

FYI, don't let Uukha know you are shooting from a Gillo riser; yes it works. as confirmed by Vitorio, but it voids the warranty.

As for the difference between the line, I did find my SX Plus were a bit faster than my SX50s, and unlike others I've had no breakage issues with my full carbon limbs.

Hopefully you can try before you buy; some like the Uukhas for string crawling, others don't for the lack of stack near/at full draw, the doubters often times find a consistency issue with full draw.

 

If anyone else is interested…

I briefly had a set of 30 long EX1’s, 30 long SX50’s, and 32 long SX100’s at the same time. When put on a 21” riser that I like to shoot in my basement(low clearance) over the same chronograph with the same string and the same arrow with a footer drawn to where it touches the springy test arm conveniently right at my draw length, the EX1’s and SX100’s both made 44 lbs on my cheap spring scale and shot 179 fps with a 450 grain arrow. SX50’s had to have the limb bolts cranked in a turn or so, but also shot the same speed at 44 lbs. on my scale. Another set of Irbis mediums made 45 lbs on my scale with the same method(but obviously a different string) and shot 180 fps. That’s not an average, that’s multiple shots at the same chrono reading. A set of TradTech RC Extremes hit 43 lbs and made 172 fps with the same setup, for comparison’s sake.

TLDR; all Uukha profiles and carbon content shoot basically the same speed for me on one specific setup. And they’re all a little step up from conventional limbs.
