You're saying you prefer the Jet-Lock style of fence with the round tubes? Like this:

Pretty much any fence can be made to work. With the Jet-Lock, they do secure at both ends...but it is easy to lock the fence out of parallel with the blade.
With the Unifence (or really, any fence), you should not need to apply a lot of sideways pressure to the work as it going through the cut. Just enough to keep it up against the fence. What sideways pressure is applied should be just before the leading edge of the blade (like with a feather board)--never further back since this can push the offcut side into the blade with dangerous results!

PS I sold my Jet-Lock fence several years ago.
