I play on ACR these days and while my biggest money maker is PLO8 I tend to gravitate towards the tournaments that have the longest structures. On ACR they have tournaments that hit the 1000/2000 mark at level 19 with others not until level23 and then yet there are a couple that hit it not until level 29, but unfortunately these are tournaments with a 5 hour late registration not exactly my favorite thing in the world.
My poker style gravitates toward the longer structures, but not the longest late registrations so I try for the ones that don't hit 1000/2000 until level 23. Three hours and 40 minutes of poker playing before hitting that level. The 15 minute blind structure hits 1000/2000 at level 18 usually,but with the longer times between blinds that equals 4 hours 15 minutes of poker play before that level so when available those are the ones I live for although they are generally 3 hour late registrations and I prefer 2 hours or less, but because of the longer levels I'll jump in with both feet first.
