Blizzard Magnum 8.1

I picked up picked up some blizzard titan argos on ebay for real cheap with the IQ 5-14 TT bindings.  I am 6'4" 250, level 7 or 8 I guess. 

I started thinking that on the smaller end of the quiver i could pick up some other blizzard skis with the IQ system and use the one set of bindings on both.  A few of questions:

1.  Will the bindings work on both?

2.  Does anyone have any Magnum 8.1's for sale without bindings?  (I will also post on gear swap).  I know its a system ski, so most offerings online are offered with the binding--looking for just the ski, new or used in good condition. 

3.  Does this seem like a narrow end of quiver ski for me given my size?  I was thinking about getting the Contact 4X4, but for the possible savings on the bindings. 

My 2 quiver skis are the Argos and Contact 4X4's.  Argos are outstanding in crud and pow...4X4's sensational on the groomed/hardpack/ice.  Unbeatable combo...for me!

You will need to find some of this years 8.1's. Next years will have the 51mm binding vs. the 37mm that is on your current Argos. Might be a tough find, Blizzard was shipping one to one ski and binding this season. 

If you happen to find some with some small Duke IQ's, I know someone looking for a pair.
