The 1/11 prayer stakers are overated, you get the occasional idiots that dont look you up, but on stakes that are like 50m+ you will never get 2x'd , so if you have a main thats close to maxed, just max it out, it doesnt make any difference what prayer/summon you are if your maxed vs maxed players.
I have a 11 prayer staker btw, so yeah im speaking from experience.
