RE: iS145 vs. FT148
Are your HPL Race Booms blue in color (the grip material) or Red.
The older blue HPL booms have 4 pulleys in the rear end, the newer Red grip HPL race booms have 3 pulleys in the rear end.
Please send your photos of the 11.0 m2 on the Gun mast to:
I'll send you back some photos of different adjustable outhaul clew rigging methods for 3 and 4 pulley booms.
I'll also have a look at the NP Adj Outhaul kit to see what components they provide and maybe we can get your adj outhaul working at about half the current effort.
Hope this helps,
