Now, I have a DS1, and that means that the tracks are mounted on the insides of the coamings and not on top.
(From the picture it looks like a 12" track)
Located as they are, and cleated off at the CB trunk
there's a pull away from the base, loading the screws on tension.
In your placement, the screws would be loaded on shear, which makes them
less likely to pull out. My old track broke when a screw pulled out and one end
of the track received bending loads it was not designed to hold.
I do like the appearance of the replacements better, perhaps just a question
of the design not looking like stamped sheet metal.
Now, the one thing I don't like 100% about my layout is that the slightest tug
on the jib sheet will uncleat it, and it's hard to re-cleat it without pushing down
on the sheet. If I had a fairlead before the cleat, that would hold the sheet
down, but then I would be unable to grab the sheet near the track, pull it tight
with one hand and cleat it (I would need always grab it on the far side of the
cleat - which is amazingly often not the best place to grab it). A solution
would be a fairlead that has an opening - so you can feed the sheet into
it from the side. However, I haven't seen such a design anywhere.
