Not too shabby!! How about using the extra points to upgrade to the Typhoon Speeder w/HB. Very Versatile and mobile, move 12/deep strike and fire 2 krak missiles or fire two frag missiles and HB for horde. i've never been a fan of the Melta/HF set up but that"s just me.
As far as the razor goes I like the LC/Plasma version here its a little more durable with the two weapon systems. Good Luck
