What do you reckon to these springs?

[kebab19]

The front dive you speak of is down to the standard front springs. Although they are dual rate the problem is that the softest rate of the spring is way too soft (and indeed the proportion of the spring it takes up is way too long) and conversely the harder part of the spring is too hard.  Combined together, the front spring characteristics are meant to be designed suit every rider but in reality they leave almost no-one happy with them.
Aftermarket springs, of any sort will almost certainly be an improvement over the standard ones. You can also address fork dive by either filling forks with heavier fork oil (15weight instead of 10weight) or by reducing the size of the air gap within the forks slightly.
