Well it seems the "stack" syndrome has finally arrived here, in the last month I've seen 2 CTDs 2nd gens with stacks, very cool! If I didn't like the sound of my 4 inch JRE I would have done it a loooong time ago, but that's my justification to get another CTD, just to put stacks on it. I've also noticed an increase in CTDs on the road, we're multiplying!!!
