Am shooting a Gillo Ghost 19" with DAS longbow limbs. I enjoy it for league though I have had issues with my Bosen limbs requiring excessive (to me) brace height to avoid noodling.
I have seen some risers listed as having better angles for longbow limbs. Is there any resource one can reference to see the relative angles of different risers? It doesn't seem like most manufacturers list them.
If I were making a wish, it'd be probably for a 15-17", low angle g10 riser to try out for hunting - heavy enough, a little smaller.

Dryad has 16 degrees limb pad and it is excellent for longbow limbs. I think White Feather Lark is around 17 degrees - my 19" works almost as good as my 19" Dryad with Dryad Longbow limbs. I run the long longbow limbs with a 7" / 7.5" BH on the risers.
Morrison has 18 degrees limb pad. I never had one to tell you how the longbow limbs work with it, but he makes G10 risers and I think the 15" will be good for longbow limbs.
There is no list for different risers pad angles - through discussions with the bowyer or the limb maker I found this information.
Interesting enough, the longbow limbs were very good on the 13" VPA I had - BH was 7.75"-8". VPA I think has a relaxed angle, around 20.

you can either spend money to get a riser to fit your noodley limbs. that will be a maybe thing. I mean it could still noodle.
You can spend money & get some longbow limbs THAT WON't NOODLE on your Gillo Ghost riser, if you like the riser. Used SKY BELCHER or new Bivouac limbs, used Centaurs, or any of the Java Mans.
I've ran SKYs and Centaurs on various lengths and brands of risers from 13" to 25".......not noodley even at low brace. I've used ONE SET of Javamans on 2 risers 17" & 19". not noodley.
YOu can get a DX5 or Bivouac Backland 15" riser to try with your Bosens.......be nice if you can visit apples to apples with someone who's DONE IT.
let us know where you go with this, always interesting.

Thanks. Yes, I have heard VPA works well. Maybe the general idea of short riser helps longbow limbs.
We should collect this angle knowledge into a referable document somehow.

Thanks for some examples. I have seen some Bivouc limbs but heavier that I should have probably.
Generally it seems people stick with a riser and swap limbs but maybe the opposite could work.
However I have found my super low grip in the Gillo is great and I might be out of luck reproducing that on some of these risers.

Yes, it your grip or for that matter how you pressure into it. Find center and tiller for there. The riser and or your grip maybe the problem. Not the angle. Bouyers build longbows with asymmetrical limbs.

I think the problem is the Bosen limb geometry: they have a lot of reflex in them and the string is almost touching the belly of the limb with a normal BH - almost like a recurve.
Refer to attached image of the Bosen limbs on the Bosen native riser. This is a snapshot from this review:

We are trying to get a BH that will push the string away from the limb because that's how we think the longbow limbs should be when in reality these limbs are not designed that way.

Interesting. Sounds like you are saying the issues I posted about in this thread Bosen ILF lssue - wtheck!? are expected

Yes. I always said that limbs work best with their native riser - even if many think I am wrong. IMO Bosen will work with other risers if they are used in the parameters given by the native riser they were designed for. Do a test: use a brace height which is allowing the string to touch the limb as it is supposed to and come back with your findings.
PS Border Tempest is having his brace height indication for Border limbs. For other limbs than Border Sid is saying to use an additional 1/2" for BH. I ran my NIKA N3 on Tempest with a BH of 9" when usually, for 25" riser and medium limbs 8.5" is in general the sweet spot. In my case, the 9" is sweet spot.

I speed-read it but did not see 15 degrees. Maybe you asked them?

It’s under the q&a tab.

Like you I would love to find a heavy, short (15” or less) riser with limb angles that would be conducive to longbow limbs. It seems like the “better” risers for longbow limbs have 15 or 16 degree limb pad angles and not much deflex.

Has anyone used the JC Optimus 15" with longbow limbs? It has a nice mass weight.

I know it's common to swap limbs for indoor to hunting seasons, but does anyone ever swap risers instead?

I swap bows entirely from Indoor to Outdoor. Why messing with tuning again when the weather gets you indoor?

It would be tuned once, the first time I tried it, just like switching bows.

Not really for me. I am lazy and I have each rig with its arrows and the tune done one just one time for my special needs. The arrows used indoor, the plunger setting and the marks on tab are different. Why doing this each year? But this is me.

If someone ever goes the Carbon Z15 route, Amazon has them for like 80 bucks less . That's where I purchased mine from when I had it for a short spell . There marketed as OMP CARBON Z15.
