yes , you are right you can shoot faster with a spyder and yes it can shoot with more power . but you have to cap bps on 15.4 and keep the crono under 280 depending what you play .
When it comes to the great rocking trigger , there is not a single touri as of yet that will let you step on the feild with it as its classed as bounce so its a waste of money . If you read the page in the pgi mag that talks about that trigger it tell's you how hard it is to get the hang of .
i use a pmr and it shoot's fool .
