CTIX is my only brilliant success - all my other's were peanuts compared to what invested here (HGSI, SOMX back in the day)  too many losers to list, haha, but I am waiting for a couple to come of age: CTSO, CVM.  I'll have to check out yours sometime when I feel like expanding my biotech investment.  I do like WHZ for the pure dividend action.  3D printing has an intriguing future (SSYS, DDD, etc.)
