Thanks. I may give another 1430 a try, and would try these carts. Having had such bad experience with my last attempt, my first question is ‘why aren’t you pushing these harder’. If there is a better way than the traditional carts surely they are the way to go for any new user.
As a complete aside, it occurs to me that Roy’s new droplet is a great way to linearise for different amounts of GO. That way you could have 30K, 35K etc from one curve.
