Hey I ahve been valve spring shopping just to gain a little knowledge and it seems that the Vasco Jet is the preferred(or it used to be) But reading on Manleys site I has then Nex-tek as being better than the old H-11.

Has anyone used these new manley springs?

Is getting a polished spring worth the added cost??

I'm concered as I want to spin my new combo pretty high and I would like to have minimal maintenace. I understand I will have to change valve springs often, but I would like to do this as infrequently as possible.

The "Nex-Tek" line has been out for a few years and they are very good springs.
