We just received a new large ECO snake guide from Snake Brand. These heavy spey/saltwater guides are .035 whereas the standard guide is .030 for sizes 4, 5, & 6. These heavier wire guides are perfect for spey rods and for heavy saltwater rods from 10wt and up.
The actual surface hardness of coating averaged 64.3 Rockwell in hardness tests, and is Saltwater proof!
Priced the same as the standard ECO guides, these are a great option for your next heavy salt or spey build.
