^^^^ This, if your friend is good on the $$$. Perfect fit as 50/50, amazing ski. If he wants to save a bit, the 2011-2013 Stockli Stormrider 95 was same shape and camber as the current, but without the reduced metal thickness and topsheet. So significantly burlier, more like the Stocklis of old, but still surprisingly easy to handle. It would fit his needs about as well. I reviewed it here somewhere a couple of years ago. He could find it on the web for 2/3 what it used to run.
If he wants to save even more $, and doesn't need early rise in front, the Stockli Scot Schmidt's from the late 2000's are still around in 188 cm, 89 mm. This one is $299 new: http://www.ebay.com/itm/like/301131040536?lpid=82 I owned this in the 178; three full sheets of metal, burlier than anything currently in production, period. Will penetrate steel armor and glide over actual coral - not the kind on ski slopes - without you even noticing, silky and precise on groomed and in crud and chop, but demands a skilled pilot. In 188, it wants to go fast. Until this year, Stockli made a wider version of this ski, SS Pro, I think it was named, that's a touch flexier. But a few mm over 100, and not as 50/50.
And if he's on the ah, frugal side, like guys here who refuse to pay over $250 for any ski, he might find some long versions of the Head 103 around online. This is not far from the real competitive pro ski, stiff and damp, good for any speed. Also more like 30/70, but will carve as you'd expect from a Head.
All of these calls are predicated on him being an expert, not a friend's assessment of a buddy who's a good skier. If he's less than high advanced, he will not much enjoy these skis regardless of his size. If he doesn't look much like how instructors ski, I'd say go for some different models, Something like the Blizzard Bonafide, last year's Head Experience 98, or a Praxis custom job in the high 90's will give him more grins-per-mile.
