Not a full ring reg, but I am a 6max winning reg and those are almost identical to my stats (semi-loose aggressive) so these seem very loose for fullring...
18/15 would be more appropriate for full ring I think...
Yeah it will be, esoecially blind v late position opens. It is something you should be incorporating also.
What is your current 3bet% Fold to 3b%, FST and Aggr Factor?
As said I a a 6max player but have quite a bit of experience analysing stats etc....
