I've heard rumors that DSA for Alps are extremely tight.
Like "oh my gosh, am I going to pull this switch out?" tight.
Anyone care to debunk this?
It depends on both the cap material and the switch stem, at least in my experience. The latter might not apply to brand new switches like Matias or Fukka switches (which will probably put a death grip on your caps).
IME, PBT caps really love gripping their switches, and it can feel nightmarish to try and pull a PBT cap from a board that's had its caps on all its life.
On the same token, if the sliders get loosened up a bit (how, I have no idea, but some old Alps boards I've brushed past have had loose-fitting caps due to the slider/stem/whatever it's called), then there won't ever be much of an issue.
The tightest switches I've ever worked with were Amber Alps switches, with both ABS and PBT. I'm sure this has less to do with switch type and more to do with wear and use, but they were scary tight. In second place is the Dell AT101 with Salmon Alps and PBT caps.
Might want to make sure the caps have no flashing on the stem. You don't want to give those naughty Alps switches more leverage to snap your caps' stems off.
EDIT: Also, NJ, if Infinity's stock DSA PBT is that scary cruel to Alps switches, I'm scared to see what they'll do to my Hammer Alps baby.
