I mounted my TSTs with Marker Dukes...now I need a recomendation for Skins.
Also how do I, do I need to? notch the tail so that the skin hook stays on?
You should be ok without a notched tail on these, and either the Black Diamond Ascension skin or the G3 Alpinist would work great (and are among the most popular skins that we sell at Backcountry). If you find that the skin isn't staying put on the tail of your TST, check out the G3 twin tip adaptor. I'd give it a go without this modification first (carrying a couple of Voile straps just in case you need to secure the skins while you're out), but this option is always there if you need better security on the tails of a G3 skin.
