yea they are, i have a now smooth back rim after having it grinded by tarty when i got my rim and my maggie needs bleeding. i trust them more with that setup than my echos on a perfectly bled brake
2 1gb sticks. you could get a 2gb and keep the 512 but i doubt they would run properly as they are different makes ect ect. 2 1gb sticks of the same make ram will do you nicely
talismoon fans: ebay. get whisper max but dont put the 12V part on, just use stock 5v bit. still better than MS's ones case: easy as piss, youtube to take it off and put new one on same as you would the original
i dont, mainly as i havnt got 1 but in all seriousness, i would wear it if i was doing something big but i havnt realy pushed my riding that much in the last year
