hello! the answer is no. you will not be able to mine more coin with pool where are less people
that is not possible, on that pool you will wait more time for finding the block, yes you'll getmore reward, but cause you have waited longer - it would be the same
unless you'll find a poll with a god damned luck like 75%
by the way, nova is stealing about 20% of your hashrate, so if you are mining BTX there- try to switch CWI or yiimp = there you'll earn more for you hashrate
