As un-fortunate as the excess weight aloft will be with those relativly bulky sta-lock toggles, you should use them as opposed to forks. Splices might be better still. Forks would be much more prone to fatigue on a boat like yours (googled Hughes 25- gotta love google !) with its bendy rig.
Sta-Loc says "It is recommended that a bar toggle should be used with all turnbuckle fork ends. " I would assumme the double jaw toggle on their wire terminal serves fine too..
