my opinion about that issue..
when u play leagues, play with "telecow/jetcow", its totally fine since HYST=NO RULES, pure tactic.
once I play with friends for fun, or even with random AG ppl, I go for 'skilled' shots with some nice style, I never "telecow/jetcow" unless it used on me before, and even if some1 doin' it, I never get pissed...
pH ftw!
