Currently they are my favorite types of MTT's on Stars. I am recently trying to grind the $4.40, $5.50 & $7.50 (the ones with relatively smaller fields which run during the local daytime for me) BB & PKO's.
Lately, also been into the Hyper-Turbo 6 Max $5.50 & $7.50 PKO's. The variance is obviously much more, but its a LOT of fun when running good. Also I think strategy for Hyper-Turbo can be very polarizing and interesting.
Aspiring to build enough roll to justify (I go by the 100 buy in bankroll management strategy) regularly grinding the $11 & $22 BBs & PKOs.
