would go for h&r but v3s are better.
But are they? It really depends on the usage imo. From memory when Naith's were being fitted, the damping isn't easy to adjust once they are on. Now if you're like Naith, plenty of track work etc you probably know what you want from them and can get them setup accordingly. But there are potentially hundreds of combo's with the 2 adjustments, so you could potentially be dicking around with them for ages.
If you have less experience, a fixed damping setup that just 'works' is better imo.
From an outside perspective you seem to be spending a lot on various bits with an eye on track work, without getting on track.
I'd rather get it on track (if that's
genuinely the long term goal) and figure out what you're no happy with!
