David -

Did you receive my reply about the 30M sloper?

IMHO,  I believe a simple inverted vee would serve you better.

Slopers are looking for some resonant length to be supplied by 
the tower/antenna.  This works fairly well on 80M with 60-100 ft
towers and large tribanders.  For example, a 3L20 or TH6/ TH7
will provide approximately 40 ft of equivalent top loading.  This
is MUCH more than the 25 ft you need for 30M.  My guess is that
you will not see a good match and have an unknown radiation

The inverted vee would provide a better match and a known pattern.
