Ok, thanks for the comments. Looks like I'll have to go with a separate tack line then!
One question though: If I put the spin halyard cleat up on the mast I will have extra leverage, but also have to reach back behind the main when sailing "odd angles" right? That would seem to negate one advantage of separate tack control...
Yes,you can only hoist on one tack and need to reach right foward to release on the drop - no good for single handing [where everthing must be able to be done whilst helming]
