Hello rodbuilders ,I've just purchased 2 GF900M and 1 GF900L blanks . They will be used for Rock fishing for fish up to 50llb .1 medium is for spinning and the other will be for an overhead reel , I havent decided on the 900L set up as yet . I'd be intersted in any thoughts from rod builders with thoughts on configuration , spacings , guide type for braided and mono line . Any other imput or advice would be fantastic !.

Regarding lining up the spine of the rod im not to sure whether to wrap the rod off the bone for extra strength or wrap it off the bone and tell the buyer his new $450 rod would over time develop a twist and the twist could effect the top 3 or 4 guides weakening the wraps or the guides . Any suggestions, idea's or thoughts anyone ?

Spine has nothing to do with rod twist. Guide orientation does. If you put the guides on top, the rod will attempt to twist no matter where you put the spine. The lever arm effect will overcome any spine effect.

Here's something else to consider:

I probaby shouldn't have used the word twist and should
've used the word permenant bend in the tip . I have observed in over 20 years of repairing rods spinning or overhead rods that if the guides are wrapped off the spine the rod will develop a bend after time towards the dominant spine of the rod . With the rod being loaded off this dominant spine the rod twists and can damage wraps and /or guides . The point of the blank that is the strongest maybe off the spine which I dont dispute . I personally dont like a permanent bend in the Rod , especially when I can prevent it . With most rods wrapped this way you can actually feel the rod twisting to find its spine when loaded which is not a good feeling . Have you been reparing and observing used rods for 20+ years or more Tom . I say this respectfull and its a genuine question .

No, I've been doing this for closer to 40+ years.

Where you orient the guides on the blank will have nothing to do with any warp developing - that's a separate issue and one that was mainly a problem with older rods made with polyester resins. Regardless, the rod will always attempt to twist so that the guides are facing towards the direction the load is being applied from, regardless of spine. You can't overrule the laws of physics.

Spiral wrap the casting rods Guides are at the 180 low point No twist

Thanks Tom for your response . On building off the spine the rod underload will try to straighen towards its spine no matter if it is an older rod or a brand new calstar 900m , this force is a fact of physics also . Maybe this force is what makes a blank 6% stronger on the static test done to determine whether a rod is stronger wrapped off spine than that of a rod wrapped on the spine . So my first question still remains relevant . Shall I build so the rod will develop a bend overtime , or shall I line the guides up on the spine and prevent the rod developing a bend or twist in it ?
