Hmm... Some drops I prefer to do on a hardtail. Mainly those to a flat landing. Mostly because I use an entirely different drop technique than I do with full suspension. I'll generally go a lot slower, and wheelie-drop landing on the back wheel first, absorbing the landing with my legs and then putting the front wheel down. In a way, that is probably the one "trials" move I can do - mainly because that technique is muscle-memory from my childhood doing stair drops on my BMX bike. I haven't really tested how big of a drop I can do this way (and turning 51 in less than a week, I'm not looking to find out...), but up to 3 or maybe 4 feet.
