I'm looking at getting one or the other in the next week or so. I was wondering if someone could highlight the differences between the two for me? I know about the silicon damping and the damped lift but is that it? I can certainly live without the silicon- most of what I've heard about it is negative and I'm not to fussed about a damped lifter, a manual lower thing will do me fine but are there any other differences i.e. bearing tolerance and such. Do they sound different to each other? Theres a rather large difference in price between them and if I'm paying for a couple of things I don't need then seems silly to get the V, especially as the IV can be upgraded to V spec if I feel the need to at any point. TIA
