I have a Troll 225, fabricated january 2002. (size by Atair). I weigh 68 kg. I jumped it 15 times with 1 jump slider up (4" delay) and 14 slider down, of which 6 were assist and 2 static line. Altitudes ranged from 59 meters (yes, the 6 assist), 85 meters (2 static-line, in order to meet the landing zone) to 120 meters.

The slider up opening was really good and on heading.

The slider down jumps were all on heading (with some 20-30 degrees to the left openings)
I had only 1 opening assist which appeared to take more time (0,5 second maximum I would say). The rest was just fine, crisp and instant. I have never jumped a V-tec modified canopy so I have no personal comparison.

Although I realise that 15 jumps might not be a significant number statistically, I have no reason to endorse the argument Tom Aiello put forward here.
