exactly. some people might even prefer a4tech or microsoft over razer.

nothing such as better for fps game or what game but everything depends on the user personally c which one suits u best

yea, agree wat spiketwo say..
u say no shop letting u to feel it? Yes there is but for logitech dun hav la..
at Sri Com , plenty of mouse for u to feel. go there n feel them but dun buy from them.. 

Nonid to feel feel test test 1 lar. When buying a mse for gaming, just go buy the most expensive 1 u like n can afford. After that it's all about getting used to it n adapting ure style of play to the new mse. When I bought my G5, I thought it'll be easy to adapt to it coz I also have an MX510. Same shape n same company I figured. But it's a totally different animal the G5. Mega 2000dpi is incredible. I cudn even aim at any1 in CSS for the 1st 2 days. The cursor was just toooooooooooo FAST.  HAhaha. Then the weight is also a lot heavier than the MX510. Hand feels tired coz of that. So, just get what u think is best n u can afford, try it few days. If really dont like it, there's always the ever helpful LYN Garage Sales for u to sell it off n try another 1.
