slrp007 What I suggest:
Monthly sub: 25 downloads/month (equiv to ~ 4/144h) for the first month. Increase quota by 25 by month until sub is cancelled with a max of 200/month (equiv to ~ 33 /144h).
Annual sub: 250/month (equiv to ~ 41 /144h) at day 1 of subscription since they paid up front.
LT: 300/month (equiv to 50 /144h).
Monthly limits are more flexibles than 144 hours limits.
That sort of plan sounds good, it rewards long-time subscribers and discourages 1-month hit-and-run downloaders (but not prevent it, for good reason)
One thing I find annoying with the current system is there is no way to bank downloads, if I go a week or a month without getting files then i've missed those download slots forever
Going to a monthly limit would be a good fix - maybe only allow it for 1 year+ subs or lifetime
