^^^^ Good find on the $199 Vagabond in the 177. I think the OP would be well worth spending a few more bucks on that softer version and return the stiff El Capo. That covers the longer softer ski in your quiver.
For your shorter stiffer ski, consider a Blizzard 8.0 Ti in a 172 for $112:
Or, a Blizzard 8.5 Ti in a 174 for $133:
Don't underestimate how much more skis those Magnums are vs. your current K2 AMP Wired 177mm (see more here). The Magnums are a little shorter but much more serious skis. There are lots of positive reviews here for the Magnums if you search. Seems like either could be a food fit for you.
And, yes I'm pushing a ski that I just bought without a demo. I just bought the 8.5 Ti in a 174. They showed up yesterday and perfectly fill the hole in my quiver between my 177 Steadfasts at 90mm and my 170 AC30s at 80mm.
Actually, I'll be retiring the AC30s from routine service. It's been a great long run with those. Here's probably my last run on them skiing bumps at A-basin June 3rd, offered as part of my ongoing case for shorter skis. Again, I'm 5'11" 180lbs and those are 170's:
