I want to be in but almost all your caps are too high. Yes, you're going to get a decent amount of variety but some of these stipulations are going to guarantee people people playoff spots and others aren't going to have a chance in hell.
For example, stipulation 3 should be between 48-52 otherwise they will be almost guaranteed a HUGE advantage over some with say stipulation 6. I like people having different caps but some need to be much lower. I would give my salary opinion on each stipulation but its your league so I won't go that far. This is just my opinion. I will say if you are open to cap changes to a number of these I would definitely want in. I love it as a rough draft.
