You get the same damage from the mast or extension. The clip is concentrating it in one spot to save you a bigger repair.
A few more pictures to illustrate how ridiculous the Chinook design is. Note how the corner of the new clip can point load on impact with the deck, compared to the round clip that has no points to load, and is far more likely to be protected by the built in mast pad. I've never had this issue in 30 years with round clips.
I've got the same Chinook as Ryan (middle in photo) but worse, it actually came with the old style 'ring-with-a-pin-on-a-string' style clip (top) and I sprung for the new 'Ryan-style' clip from a shop cuz it looked like a better design. I'll reinstall the old one.
The Chinook on the bbottom has Imax style. Hasn't seen any use as I don't yet have an SDM mast.
the Simmer on the top is actually my favorite, and it has the clam style clip. Will be buying more of those clips I think.
Off topic, the reason I like the Simmer is because the pulley and cleat mechanism is so small, the cleat is closer to the centerline of the mast than the Chinooks. As I get close to max downhaul, the line is still pulling the tack straight down. With the Chinooks, the line is pulled away from the mast in the last few CMs.
