Alex,
I know you'll probably not like the following but:
I intend to purchase from your goodself a SL2 at 35 ft come early summer.
Now I already have 3 x 12 ft Omnipole alloys. (These are nos 1,2 & 3, and so are reasonable in weight)
I only have a couple of jobs where I need 60 odd feet & so would it be possible to add your sections onto the powerpole?
When I have enough work to warrant the extra SL2 height then I would buy the extra then.
What would the dimension of the 35 ft base section be!
( I'm ok with this bring outside the warranty guidelines)
Thanks kevin.
