Unfortunately, this argument comes up again and again, and the solution is always the same. Flip got it perfect with this response.
My 2 cents.
No-one likes change, and I love the old school trails, but in the last 7-8 years I've been doing a lot more building, and one thing I've come to realise is that what I loved in techy trails, is really just really shit, totally unsustainable trail alignment. It's fun for a while, then it just gets blown out, trenched, wet, the wood gets polished and worn and the rock also gets polished and just dangerous.
The problem is, people still want this, but with the current volume of ridership on the shore, it's impossible to sustain this for even a short period of time, since even beginners will think that they have the skills and will then go try the trail, skid, braid and walk their way down the hill, damaging the original line.
The only thing that will work, is to keep the advanced trails on a different mountain. Cypress is a perfect venue for this, and it looks like Gord and Alan have things really sorted with their approach.
Also, if you still want old school tech, there are a couple of options on Fromme that are still perfectly fine (eg. Grannies), or, you can travel half an hour and you are on Eagle or Burke where there are lots of great old school options, some of which (Nescafe) aren't super steep, still really technical and probably moderately sustainable given the current ridership volume.
