Can definitely notice a different feel/spin with light long cranks vs heavy long cranks (I’ve used milled longer cranks for a while) but as Nurse Ben pointed out +/-200 grams on the tire creates a much more noticeable change… though like a lot of things on the uni, after a ride or two what you’re now using becomes the norm, how much it all matters apart from being great fun to play around with, hard to say!
As for the Ventures being strong/durable enough for those kind of drops - I don’t know TBH. They are a neat looking, light and cheaper alternative to Moments but they aren’t bombproof like Moments e.g. Nimbus Ventures
Kris mentioned somewhere a while back lighter Moments were being tested. I hope that ends up happening as I reckon they would be popular.
On just about everything though you trade one thing to gain another, so really it’s whatever suits you.
