running backstay leads

[brboater]

For a 25' Virtue sloop, 11000 lb displacement, 300 sq. ft. working sail. Replacing the galvanized vertical lead blocks for the running backs. Option 1 is to replace the blocks with new SS welded blocks like the original and continue to use 7x19 wire. Option 2 is to replace blocks with Schaefer vertical lead blocks and switch to HM rope stays. The smallest, M-66 block is rated for 2800lbs and costs $126. The M-82 is 5000lb, $200 and the M-100 is 7500lb, $320. Sheeve dia. are 2.6", 3.2" and 4." These back stays work with Highfield levers. I don't care for tackle adjusted runners. I'm very interested to hear comments, thank you.
