I have not completed my research on all products avaliable but have a few comparisons. I have coosa , corecell and Nidacore. I am have run into a dead end on Diab products which makes divinycell and kegecell. Diab refered me to Paxton distributers in Norfolk Va. so I visited them this week to only find out that they didn't do retail sales and no body there realy had any knoledge of the products except pricing. They refered me to Norfolk marine and I found out there they had only a catalog and no knowledge on the products. that put me back at square 1. I haven't given up yet ,I e-mailed my contact at Diab telling him my experience and i just got a response saying I can buy direct from them and wants to answer any questions I have. Nidacore also refered me to a suply house in Norfolk called Eastern burlap and trading. I was impressed with the knowledge and willingness to help although I had told him upfront I was comparing products for my small project and wasn't gonna buy anything until i had all product info that I could get. Not only did they have Nidacore but also had coosa and corecell. He gave me samples of coosa and corecell. After I told him I had heard not to use Nida HP88 as core he didn't agree telling me he supplies Fountain powerboats with this product which they use for core . I am triing to confirm that but if true I think it should work for my stream. In the Nida honycomb site there are several builders that use Hp88 for core such as Bertram and Edgewater along with a offshore racing style boat that I couldn't make out the name. He seemed not to be partial to any of the products and just wanted to help. He answered any question I had no mater how stupid it was. He did not recomend H8pp unless i doubled it to a 1 inch stringer because of the small height. He suggested I use coosa for the stringers if I wanted to maintain a 1/2 inch width. He said all of these products would do fine for the core but since i am looking for max speed i should consider wieght which would put Nida in 1st place with H8pp.Hippie459MN wrote:Whats the cost difference on that vs standard core? I thought about going with that as well to avoid any future rot but Im not sure what I am going to do just yet.
