My third build will be on a Batson SPG842, spin set up. Are there any things I should consider when building on glass versus graphite? Can't find anything on it in my book.

Also, on my current guide layout I'm using Forecast M's for the stripping guides and Forecast F's for the intersect and out to the tip. The transition from the size 8 M to the size 6 F seems severe next to each other but not layed out. Anyway I came up with 9 guides. Is that too many for a 7 foot rod?

Thank You

Luis,
Glass has about 4 times higher strain energy or toughness than graphite so the location and number of guides for stress distribution is not at all critical. This means that you can use fewer guides on glass than on graphite if you choose. Also glass due to the lower modulus of elasticity, higher weight, will have a much lower resonant frequency. In other words it will be less responsive, slower reacting, slower to damp and be less sensitive. Fewer and smaller guides because of less weight will partially offset this. All of this argues for using no more guides than absolutely necessary. I would guess that 9 guides is way too many on that blank. In fact, I think that you will be much happier with the rods performance with about 6 guides and could probably get by with as few as 5.
